[dns-operations] DNSSEC validation failures for reverse delegations?

[Sebastian Wiesinger]

Hello,

since last night around 0:30 CET I'm getting sporadic validation
failures for a hand full of reverse delegation. Not many but a few
each hour, from seemingly unrelated delegations:

Any idea what's going on? I'm not sure it's something interesting but
I hadn't had messages like that before and now I get a few every hour.

Regards
Sebastian
