Lol my speeds are much worse than your guys' speed. 5M Down 0.5 Up. Most people that buy T1s do it for the reliability rather than the speed. It's pretty slow compared to most offerings nowadays. $300-400 a month for a T1 in most areas. A lot of services like RR, DSL, etc. claim they are faster than a T1. They usually are, but if anything goes wrong or if it's running slow, it takes a lot longer to get that issue resolved.
With my speeds, you can see why I avoid cloud services.
Another common practice is to use one fast cable service along with a T1 line to ensure high speed and reliability without shelling out 5000 for a T3 line. Dual WAN routers are good for that.
