Sprint is a tad slower but always consistent. We found that during the
changing of the guard at MCI, they were constantly loosing routers so we had
to fall back to Sprint for our upstream.

I'd recommend running dual systems for about two weeks and slowly moving
traffic over to the new IPs until only your Mail, FTP, WWW, Primary and
Secondary DNS servers are the only machines on the old subnets. Then just
kill the old subnet and move on without a hitch.

Please note that if you have colocates, they will need to make sure that
they update their records with internic also.
