Dear Job,

I analysed the alert, here is my assessment.

Thanks a lot for the analysis.  I had also received the alert (Randy
Bush and others as well, see "Subject: TA Malfunction??" thread :-) and
was wondering... your analysis makes sense as far as I can judge (which
is not very far).

[...]
It is interesting that the 'trigger event' happened two days ago, but it
is only just now that it became quite tangible! It seems this anomaly
could've been alerted for earlier on.

Can you elaborate how? (Looking for overly-large or otherwise suspicious
manifests signed by CAs?)

I noted in my "RPKI's 2024 Year In Review" report:

Thanks for that one as well.  It has interesting information and
reflections that should be discussed in the operator/sidrops community,
preferably by people more knowledgeable than me...

Cheers,

Simon.
