A rerun fixed it.

Comment 1

[Pete Moore [:pmoore][:pete]]

Indeed that is very weird.

Let's leave this open and see if it happens again. Perhaps caused by a solar storm?

I'm guessing no recurrence?

Comment 3

[Jordan Lund (:jlund)]

afaik no. can close for now. will reopen if it starts blocking again.
