Thursday where? Wasn't it Friday in Thailand already?

Where the server lives it was Thursday. Where you live is irrelevant

mersenne.ca is back online, at least for right now. Turns out the server was overheating (not my fault, I'm not running mprime on it or anything) and causing the crashing. They've swapped my drives over to a new physical server and it's back online. I still need to rebuild the RAID, so there might be a reboot or two coming today, but otherwise it should be back online.

It wouldn't hurt to re-submit any TF>1000M results from the last 3 days. They've probably been received, but just in case it doesn't hurt to resubmit them.

Depends on your definition of "vast", but yeah, it's about 600 million records taking up ~50GB (with indices). Of that, however, most of the data is replicating stuff already known from PrimeNet. The "important" bit is the TF effort above 1000M, which is not duplicated on any other server (but is backed up monthly to my home systems). Once the server is back online, if there's interest I can quite easily make this data available to anyone who might be interested (at a public URL, there's no secret data here).
Q: Does the server at the remote location perform backups more frequently?

50GB. That is not as much as I would have thought. My external HD would easily accommodate that. I wouldn't mind being able to peruse your data, once in a while, just to see what it looks like.

I just checked. Your site is back up and running.

Yes, the site is back up now and should stay up, hopefully. There may be a reboot or two later today (8h from now) as the RAID gets rebuilt, but otherwise it should be back online for good, running on new hardware.

Disk storage is cheap. PrimeNet could start storing this data too.

SQL dumps of factor tables are now available at:
<redacted> (~3GB)

TF limit for all exponents now lives at:
<redacted> (~600MB)

I've set it to regenerate these files early in the morning of the 15th of each month.


edit: (2019-Jun-25) the collection of data export downloads are now available at https://www.mersenne.ca/export/

Can I assume we will start seeing current data again in a day or two once RAID is rebuilt?

Data will catch up automatically, yes. I'll check in the morning to make sure it's all up to date, otherwise I'll run the missing days manually.

I've noticed that the Brent-Suyama factor page is working again too!

It had caught up two of the missing four days by itself, I gave it a push and updated the other two days, so I think it's all current now. Let me know if you find any missing data.
