Tier I Vs. Tier IV
Oct 12, 2007
I've been doing some research about Tier I vs. Tier IV datacenters, and generally understand that Tier IV is preferred over Tier I. However, in searching for new webhosts, I've noticed how some hosts brag about their Tier I network/bandwidth/connectivity/etc. So... am I to understand that Tier I bandwidth (etc.) is different from a Tier IV datacenter? If you were opting for uptime/reliability (rather than tons of ridiculous bandwidth and space), what combination of bandwidth/datacenter/etc. would you go for?

I've recently been having a few discussions with potential clients that are very interested in hosting only in Tier IV datacenters, as they see that as an arbitrary 'standard for greatness'. I'm referring to the data center tier levels as laid out here

Our datacenters are between Tier III and Tier IV; the Tier III aspects are there because of concious decisions on our part in fact. In talking with others I've been told that Tier IV datacenters are rare but I've not be able to find any myself. I think it's more difficult because I don't really trust what technicians from other companies say - they may mistakenly believe they're Tier IV when they're not - so the question is, does anyone know for certain what datacenters in the US are classified as Tier IV?

Who defines Tier 1 provider definition?
I am seeing multiple definitions and seeing various posters argue and make claims against Tier 1 and who is/who is not and how many total, etc.. I do not think that there is consensus out there. Personally, I see more than 7 Tier 1 providers and know several other very good Tier 2 or Tier 1b providers.
Many on WHT claim that there are only 6 major Tier 1 providers, but I recently had a CTO who has been in the business since 1996 tell me directly that there are 9 Tier 1 providers. I know that some providers themselves claim to be Tier 1, but many of us “know” that they are not really Tier 1.
So, who are the best Tier 1 providers out there?
Who are the best Tier2 or non-Tier 1 providers?
Who are the best providers to/in Europe? …South America?
