I don't have a server with them (I may at some point, I don't know), but I've dealt with Russell from InfoRelay (those are all the same company in the end) and he just speaks volumes about their customer support - very friendly, knowledgeable and easy to deal with.
WTF? Dinix.com isn't in Equinx AFAIK. Then again, why would you WANT to host your sites with those clowns? (you can do a quick search to see what I mean).
Yup, they're actually hosted in WebHostPlus' data center with good 'ole HE (single homed!) bandwidth

Steadfast Networks and Defender Hosting are too equinix companies (Chicago and Virginia respectively) that I would highly reccomend. DefenderHosting is a little bit pricey, but well worth the money, and Steadfast Networks has an amazing network and excellent server management.
Serveraxis.com - Cheap server, fast, excellent pings. Just got one myself. Support really go above & beyond the call of duty. Would have to be the best support I have come across with my many years experience hosting. This was my first dedicated, and I hammered them with questions, but every single one was answered patiently and accurately within no more than half an hour. Couldn't be happier with my choice.
