-p3 didn't contain any changes to DNS lookups
-p2 however did include a fix to unbound.

Its still very unlikely that either of these caused a breakage as we 
would have had a flurry of reports before now if there was an issue.

Given this I would recommend you check for an unrelated issue, possibly 
configuration else where?
