I too noticed that. After coming back up, there were 16 workers crunching certificates instead of the usual 4.
I guess fdb was taken down momentarily to start the other workers.

I am getting 503 Service Unavailable ATM.

Me too. I think Syd is doing maintenance on it. Maybe he's adding more disk space to help the DB run better.

Site's down.

There are two ID's for the Fermat number F26:

Are there issues with certificate uploading at the moment? I've tried, on three separate occasions, to upload a 37 MB certificate, with no indication of validation in status. Is there a weekly maintenance I'm not aware of?

The following numbers appear to be cross-referenced erroneously in the db. This is shown using either the short or long form for each number, so it doesn't appear to be an expression evaluation error:
[code]
[URL="http://www.factordb.com/index.php?query=72%5E53"]72^53[/URL] should be (72)^53 = (2^3 · 3^2)^53 rather than (2)^318 = (2)^318
[URL="http://www.factordb.com/index.php?query=72%5E59"]72^59[/URL] should be (72)^59 = (2^3 · 3^2)^59 rather than (2)^354 = (2)^354
[URL="http://www.factordb.com/index.php?query=72%5E61"]72^61[/URL] should be (72)^61 = (2^3 · 3^2)^61 rather than (2)^366 = (2)^366

[url]http://factordb.com/index.php?id=1100000001046468738[/url] is listed as PRP, but it is composite with the factor 17756960164157539411. When I report the factor, it returns that the factor is already known.

chris2be8 2020-10-14 16:07

That's a known problem due to factordb not interpreting ## the same way as the software it uses for primality testing. Syd has been told about this but hasn't found time to fix it.

In the meantime assume any PRP in factordb containing ## is probably not prime. But there's nothing else we can do about it.

Perhaps related, the status page shows the database disk usage as "46MB (0.00% used)".

As an aside, can we get English error messages instead of me having to look up "Fehler"? (In retrospect, it's an obvious cognate of "failure".)
