I also take issue with the statement "it would've only impacted
misconfigured sites" since we also had a check from within Postfix and
had all of our mail blocked until we figured out what was going on
simply by the amount of time no mail was showing up in our inboxes.

postfix reported nothing, so must check for appropriate response

to know every DNSBL's response codes.
Our only alert was an internal monitor on our own IP's - just basic
check script in perl, that's what alerted us to the problem, and as
its a monitor not a block its handy to see if *any* errors occur, and

According to reports, any query for *.spamcop.net resulted in an A
reponse to a landing page (there were no NXDOMAINs), so when not
specifically checking for 127.0.0.2 but just for a positive reply,
any query would be seen as a hit. As such, the incident would have
only impacted misconfigured sites.

I've received a report from someone that said that all IP lookups against the
SpamCop blocklist resulted in blocks during this time. Did anyone else have the
same observation? I'm trying to figure out if this person has a bad blocklist
lookup implementation (saying an IP is in the list, as opposed to returning an
error, when the blocklist DNS is unavailable), or if it was something larger.

We have the domain back now, but we have to wait for propagation delays. If
you query the name servers they Arne mentioned, that should give you the right
IPs.
Sorry for the trouble, folks. Now I have to go see who needs flogging.
