Comment 14 for bug 469376

Pat,

I remember having a ton of DNS issues for a while (they're all cleared
up, but for the life of me I wouldn't be able to tell you how), and
all the resolv.conf stuff sounds all too familiar. I use static DNS
(OpenDNS is a good DNS server, Google has a DNS server too) and I
haven't had any troubles for 3 weeks so far.
