It was more than 85 hours that they weren't resolving. It seems to be
resolving properly this morning (after 4 days).
I'm conflicted. Part of me feels guilty for posting the plea for
assistance on this list, when it could be as simple as Comcast
respecting some relic of a TTL and refusing to update their records for
4 days. But I'm still angry that they couldn't simply refresh their
cache when asked if this truly was the case. This effected hundreds of
I've felt for a long time that many of the implementations of DNS have
been extremely lame. So many instances where one nameserver goes down,
and the second nameserver is not queried by caching servers, or by the
client PC/device. Seriously, what's the point in having backup DNS
servers if they are not used when the primary is failing? And, if a
cached nameserver is failing entirely, why on earth would you not go
back to the root servers and refresh your cache? Google and many others
have obviously figured this out, why can't Comcast?
Thanks again to those who assisted with this. Very much appreciated.
