my company currently has 2 T1's bonded, and they are considering using Comcast.
has anyone tried Comcast? i thought with a T1, you don't have a degrade in speeds with several people connected. but with Comcast i thought i heard that it does degrade. my upload and download is about 2.6 mbps
Comcast has a 50mbps down and 10 mbps up, that i am interested in.

    On any connection, the users share the bandwidth.  The Comcast connection is probably specified at "up to 10Mbps" like ADSL is where the T1 pair is a fixed 2.6Mbps.  A lot of people use Comcast with many varying experiences with them.  If one of your business neighbors uses Comcast, it would best to talk to them.

    I've been using Comcast for my business for about 6 months now. Formerly had AT&T, then Knology.

    AT&T had the best uptimes and Knology the best customer service. Comcast has been only "OK". Outages are rare, but if you ever have the misfortune of calling for help, stand by for a very frustrating experience. Incredibly long wait times (45-60 minutes) before you even talk to a human, then said human can do nothing but read from the prepared scripts.

    My contract is up in six months and I am already researching their replacement.

    Your performance is more likely to be variable with Comcast, but it will still be faster than your T1 lines. My Comcast connection just went down and I had someone reboot the router. This seems to happen every few weeks, in the middle of the night, which is very annoying. My customer service experiences aren't as bad as younghv. I wish that it was more reliable, and I am glad that it is only a backup connection.

    Why not try Comcast as a backup connection and run both connections for awhile before dumping your T1s?  That way you could selectively turn off your T1s to see how life is with Comcast as the primary connection before pulling the plug on them.  The speed on a cable connection is going to vary greatly according to the traffic in your local area.  That means that you probably won't have many speed issues during business hours, as prime time for network usage is probably going to be 6-9 am and 6-10 pm.  If business hours are squeezed between those, you may have a good experience, but it would be worth running a parallel system for awhile before deciding.

    Excellent comment! (Wish I had thought of it.)

    We actually are going to do the two connections in tandem
    I opened a different question to see how to do this. Turns out I could just have two gateways, one will be distributed by my DHCP server, and the other, I would just manually enter.
