For you, no. But for those who have multiple ISP's as well (like us), that
does present a problem. Anybody who has UUNET/ALTER.NET as their ISP
automatically goes through our saturated and slow T1 line from
Norlight. While they're working to get the new Centurynet online in
Illinois...we have the problem of anyone freeding from us via UUNET
experiencing large latencies..and data dropouts. So, it's kind of
weird. Personally, I think our T3 provider (Genuity, formerly BBN,
BBNPLANET, and GTE Internetworking) is awesome, and I'd rather just have
the T1 shut down until there is a problem. Oh, well.
