I don't know if this applies to you, but about yesterday my
PC's stopped working w/r/t DNS lookups. Comcast changed the
IP addresses of their DNS servers. For a while they had one new
one, but one of the old ones worked. But yesterday the old IP
address stopped working completely, forcing me to update my
configuration files...
