Yeah, there was another downtime, obviously fixed since.

However, just to clarify on the debugging technique -- as I mentioned
the other day in this thread, you're dig'ing up the wrong name.


sought.rules.yerp.org is *NOT* supposed to have either an A nor a TXT
record. Only with the reversed SA version prepended it does have any
record at all -- a TXT record encoding the latest channel version.

  $ host -t TXT 5.2.3.sought.rules.yerp.org
  5.2.3.sought.rules.yerp.org descriptive text "320769313"

The actual http mirror is not necessarily in the same domain, and
usually *not* the channel name (your dig above). The mirrors are cached
in the MIRRORED.BY file, and can be checked fresh with a DNS lookup:

  $ host -t TXT mirrors.sought.rules.yerp.org

Bottom line:  Please stop digging the channel. :)
