Are you also buying a static IP? Did we get the the bottom of the terms 
of service issue that was brought up on the list before? I'm still 
skeptical of Verizon explicitly stating in their terms of service that 
they won't block ports and will permit servers on a business class service.

I'm thinking of jumping ship from Covad DSL. I've gotten sick of their 
inability to fix an intermittent problem that's be occurring 
occasionally over the span of like 3 years.

Every once in a while my DNS stops working for hours at a time. Looking 
into it I find that I can do queries via TCP, but normal UDP queries 
result in a server timeout. This is true no matter what DNS client I use 
and no matter what DNS server I target out on the net. I thought maybe 
they were dropping all UDP packets, so I coded up a custom traceroute 
program that uses UDP packets, and it showed normal connectivity to the 
DNS servers while the problem is happening. It's almost as if they have 
a transparent DNS proxy that's occasionally dying. I'd be curious to 
know if anyone has a theory as to what's broken.

When the problem happens I call my local ISP that resells the Covad 
service, they open a ticket with Covad, Covad takes a half day to get 
around to looking at it (their policy is to respond within 24 hours to 
problems affecting single customers), and by then the problem has 
resolved itself. The inability to talk to Covad directly essentially 
makes this problem impossible to fix.
