Cogent's network seems "OK", for now.
I've received several responses asking for details on how I would avoid
Cogent. It looks like getting a connection to the AT&T network will allow
us to serve our customers on their DSLS and use their direct peering to the
Time Warner network for our customers with cable Internet.
If anyone has any ideas on how this will work, please let me know. For
instance, do most networks prefer to keep packets on their network until
closest to the end point or might a network just send the traffic through
cogent in another part of their network a few hops away?
