You need an AT&T land line in order to get
DSL service!

I co-​lo my server in their facility and have been extremely happy with the service. Their cabinets are located in a very nice Level 3 facility near I45 & Beltway 8. It’s always nice to have a place local so you have easy access to your server in case of repairs or upgrades.
They offer a wide range of services, colo, dedicated, and cloud hosting. Prices are very competitive, but again being local is always a plus. When you call it’s nice to talk to one of a handful of people, all of which know what they are doing.
They also have DSL service, which I was extremely happy with. Unfortunately with the times I needed something with more speed than DSL offered so I ended up switching to one of the big carriers.
I know several other people that co-​lo their equipment with Optimal Link and they too have been extremely happy with the service and prices.
