Colo Datacenter Complete Power Outage
Jun 22, 2007
how often does a colo provider's datacenter go down? I'm not talking about resellers or their racks, but the primary provider itself.
This has been the 2nd time (this year I believe) that my datacenter at NAC has suffered a complete power outage [url], their backups failed, and my entire rack of servers were power-cycled.
Luckily I am not a web host but I am running some critical public web services/sites. I have all of the equipment to manage my own colocated machines from afar (monitoring, remote reboot hardware, and KVM/IP hardware for all of my machines) but I'm dead in the water if my datacenter's power is out.
I always ease my pain throughout a network outage or power outage by visiting DSLReports. Their HUGE website is hosted in the same datacenter (probably in the same room) as me and while it is a terrible thing to say, being able to share the downtime with a bigger fish is easier for me to handle.

I have been reading the manual for a while, and I'm still not quite sure if I can do this with AP7930.
After power outage, I don't want all outlet to power on at the same time when the power is restored. Maybe 30-90 second gap between outlet power should suffice.
for example :
00s - power restored, port #1 on
30s - port #2 on
1m - port#3 on
1m30s - port#4 on
... and so on
The only option I see in the settings is "Power On Delay". I'm not sure if this delay only applies when I submit "On Delayed" action, or does it also apply to when the power from the provider is restored.

my freebsd server suffered power outage and now at boot it shows
BIOS installed successfully!
strike F1 to continue, strike F2 to go to setup utility.
FreeBSD installed
Default 0,a (o.a)boot loaded
Boot:
But that is it, it does not respond to ping or ssh?

On the 30th we experienced downtime on a colocated server in a UK DC we did not know about it till late afternoon
when we finally got to access the server
we found the OS was corrupt
we found 2 of 4 hard drives apparently trashed
we found the backup also corrupt
so can we claim as its a mechanical failure on the DCs end?

Has anyone come across this before?
We are allowed upto 8 amps (240v) in our rack in a DC in London and the rack has a power meter. The power meter reads 6.9 amps but I had an e-mail from the DC saying that using their calibrated power meter we were drawing 9.6amps!
That is quite a difference, I've measured the kit I've put in there before using a cheap power meter and 6.9 sounds about right. The data centre is over power and cooling requirements I reckon and they are trying to get everyone to reduce their power. In fact, I've been told that at renewal I'll have to go down to 5 amps for a whole 47U rack!
Which figures should I believe, they are a major ISP but it all sounds a bit dodgy to me.

All our racks had our power reduced from 250V 13 A to 250 6A. I have checked with other datacenters in Singapore, most seemed to be doing this.
Hows the situation in other countries? Is the datacenter charging you extra for the power or reducing the power for your racks?

Just colocated at HE.NET and the the 15 amp limitation is a challenge. I'm just wondering what tricks there are to reduce power consumption by computer. Maybe people can add their tricks to this thread.
I'm experimenting at home right now. I got one of those KILL-A-WATT meters. (Egghead $18 - they are GREAT) And I'm measuring power usage with different configurations.
One thing I noticed is that the bios "cool and quiet" setting make a big difference. At idle current drops from 0.90 amps to 0.67. Of course if the processor is running 100% this probably goes away but if you have a cabinet of server and not all of them are maxed out all the time this should add up.
I'm using OpenVZ virtualization which allows my to use hardware more efficiently.
Just wondering if any of you have other tricks that cut electrical usage. Might have to put quad core processors in all my servers for expansion. Wish AMD would get their act together and get high speed quads out there.
Everything I have has 8 gigs of ram now.
Any hard drive setting I should know about?

1U colo, 1 mbps, 1 amp power in major China cities
Must have premium, mulit-homed bandwidth, with great connectivity to the US
Must have local cable TV cross-connect via coax, s-video, etc.
Prefer remote reboot
Some or all of the following:
Shanghai, Beijing, Chongqing, Tianjin, Wuhan, Harbin, Shengyang , Guangzhou
OK to have colo and cctv cross-connect in one or more cities - you dont have to do them all.
We do NOT need colo without the cctv availability.
Will need a /30 address space.

a dell 1750 with redundant power supply that has two plugs on the back.
But...
Looking at 1U colo with only one plug available for the 1U price.
Is the only solution to use only one of the two power supplies in the Dell 1750...?

I had a 12 hours outage in one of my VPS. According to the report of my provider, a maintenance task reported an error on the fsck Linux command.
Now I wonder if this error can occur on any RAID hard disk subsystem? Should I stay with this company?

I manage and develop an e-commerce site which the original designer had put on Media Temple. Their grid service and general marketing looks and sounds superb. This is no doubt why a lot of people go with them.
For months now they have been giving my client problems. People in certain places can't access the site because MT are always up to tricks moving the servers around. On top of that their MySQL performance has latency issues which makes most pages load slowly.
I decided to move the site to Knownhost(vps) who seem to offer good service at a reasonable price.
Before I could even begin to transfer the emails to the new server I get reports that the site has been down for over 24 hours. The site is still down after a whole day. This means my client can't sell their stuff and I can't transfer to the new host either.
I called MT and they offered free hosting for a year. I don't think it's worth it. The uptime and service and performance I've seen has been no better than $5/month shared hosting. For a site like this I don't think it's worth risking uptime (and therefore sales) on a company that can't get their act together. I've never had downtime from any other host before, let alone multiple times like MT.
I'm putting this out there just to warn any people who may be thinking of going to Media Temple.
I would be interested to know others experiences with Media Temple.

Anyone else notice the huge outage at Surpass? My sites went down as I was editing one, and checking the server status returns a very, very long list of downed servers. Since the Surmunity Forums appear to be down as well, I was wondering if anyone here had found out what was up via other means, and whether or not there is any estimate on when it might come back up.

I'm kind of annoyed. Not so much the server outage; I know those happen.
What is annoying me is the inability to get anyone on the phone.
I've been calling each of their 4 numbers in succession for the last 45 minutes. Finally connected with someone who has no idea what's going on, only that it is allegedly affecting their entire customer base. Man, if you're not going to answer the phone, at least put on a voice message, or maybe a banner on your Account Manager page.
their site didn't go down, just the ones they are hosting.
I'm a newbie at this so, for the vets, if you are experiencing a server outage, how long do you give your hosting company to give you an answer before getting "assertive" on the phone.
It's not a big deal to me since currently I only use my site for email. However, there must be some folks losing a bit of cash by being out of commission for an extended period of time.

To make a long story short, as a consequence of the outage we lost some of our advertisers, and right now we cannot afford our old server. We decided well in advance to delete our server, so early this week we contacted the customer care and asked when we were supposed to enter the cancellation ticket to have our server removed before the billing date (June 22). We were told to post the ticket on July 19.
We did better than that. We posted the ticket shortly after this first chat. On July 19th, we went into servercommand, to find out that the cancellation ticket was no longer there. I rushed into the live chat, and was told that the ticket was lost because we had not posted it in orbit. Ok then, let me post it immediately in orbit then.
Well, unsurprisingly, Orbit was unavailable in that moment. We told the live chat tech, and basically we were left hanging on the chat for hours until we were able again to access the orbit system. the Live Chat person said she could not enter the ticket for us, so we had to wait for orbit to load for us again.
Well, guess what? Orbit loaded again for us, but exactly after the Midnight, so it was now effectively the 20th, no longer the 19th. Nice, uh? Do I smell something fishy here?
So, I went to the chat today, and here is the reply:
Quote:
Please wait while we find an agent to assist you...
You have been connected to Daniel W.
Daniel W: Hello. How can I help you?
Customer: Hello, I need urgent help. It is the third time I am attempting to delete a server, and cancellation is sitll not going through as it should
Daniel W: ok, what is the account id and password? and the reason for cancellation?
Customer: <<snipped>>, H1 outage
Customer: I had sent another ticket more than 1 week agoi
Customer: but it went lost, for some reason
Customer: so I spent two hours a couple of days ago with one of your guys to send this other ticket
Customer: but I see that the cancellation date listed is July
Daniel W: Before I can transfer you to another department, I will need to confirm your account information. Please provide you Orbit/ServerCommand login and the last 4 characters of the password.
Customer: while we wanted an instant cancellation
Customer: <<snipped>> / xxxx
Daniel W has left the session.
Please wait while we find an agent from the Customer Service department to assist you.
You have been connected to Andrew S.
Andrew S: Hi! Thanks for conacting The Planet's Billing Care Team. May I please have your Login I.D. and last 4 characters of your password to Server Command or Orbit please. Please feel free to ask about our promotions
Andrew S: one minute
Andrew S: I am reading you last chaty
Customer: <<snipped>> / xxx
Customer: ah ok
Andrew S: Please give me a few minutes to look into this for you. Thank you.
Customer: thanks
Andrew S: I will have to get my accounting department to review this for you. It has a July date for cancellation because the server cancellation ticket was put in in less than 48 hours from the billing date.
Andrew S: I will have them review this issue for you.
Andrew S: How else may I assit you today ?
Customer: I sent another ticket days before, and it was lost. On July 19 I came to talk about this with one of your techs, and we were unable to access orbit
Customer: They said to wait until orbit was available again for us
Customer: This should all be saved in your logs, I hope
Customer: So, what should I wait for?
Andrew S: I am creating a ticket to the accounting department for them to give you an answer on the cancellation date
Andrew S: ok sir How else may I assist you today ?
Customer: Nothing else, thanks. We will be waiting for the reply.
Andrew S: Thank you for choosing The Planet again my name is Andrew and I hope you have a great day!
Thank you for using InstantService. You may now close this window.
Your session has ended. You may now close this window.
Not bad way to answer a customer who has been with theplanet for 7 years! Not only I am NOT bitching about the advertisers I lost because of the outage, since that's our fault, but I must also go through this strange - not to use another word - issue. I spent HOURS this week just to (not) being able to delete this server. I hope the fact of posting this on WebHostingTalk will help us and others in the future.

They make me wait no more than 15 minutes for support responses and I have experienced no downtime whilst being with them. Why does everything have to be so good?
Now, being serious about it:
I ordered my VPS with them two months ago because I wanted to cut down on the amount of servers that I leased. The deployment was completed within about 8 hours, had to wait for good old Otto to be deployed onto the world wide web.
I submitted some issues regarding a bit of drag in the network, slow response times etc and they responded promptly explaining the current packet loss issues with Limestone and all seemed to be resolved within an hour or so.
The ONLY issue I had is that their WHMCS, which might I say is nicely designed right now, forgot to invoice me! Other than that, superb experience all round!

do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.

I just updated my mod_security rules to version 2 with the new rules from gotroot.com. I simply included them all. I know before with their 1.95 rules I had to sit and delete tons of useless rules as well as having to delete rules that interfered with peoples web apps.
So I figure it may be different with new version. Is anyone here running these rules on a hosting server? Doesn't matter cpanel or whatever, just an average shared server with moistly php/mysql sites.
