No. It doesn't have to do with FactorDB specifically, it's just mass false positives that Avast seems to had in the last ~12h and it was resolved as of definitions update 181022-12

This number seems to be a false PRP.

Primo says this number is composite. (the Base-2 strong Fermat test failed)

PFGW 3.8.3:

Code:

(5^3989+1)/131221457898 is composite: RES64: [AB337180E6B066ED] (0.1194s+1.1703s)

Fixed now! Thank you. <3

Yeah, these turn up in FDB all the time. Just open the primality section, enter base 3 and click check base.

Also primality certificates don't seem to upload

FactorDB appears to have started ignoring submissions of moderately large numbers of factorisations (as you tend to have if you've progressed an aliquot sequence by a few thousand terms); I paste the terms into a 'report factors' box, and I get the 'report factors' box back again without the factors being recorded.

I'd contacted Syd last night. He wrote that some updates were installed.
After updates, the website came back but indeed cert upload stopped working, which I'd let him know.

The time and date information for prime factors in aliquot sequences now all reads "Before November 4, 2018, 12:20 am" unless completed after that date/time. This must be part of a general reset of the database.

It's still not working for me; the previous version, where I couldn't submit using wget but I could submit thousands of factors at a time manually, was almost acceptable. At the moment I don't seem able to submit more than twenty lines of factors at a time, and this is useless.

It seems like now HTTP POST request size was limited by Apache or PHP to ~15Kb.
