Sometime early this morning, our database started having issues, most likely due to a disk corruption issue.

Unfortunately the postgres database was unrecoverable, and we had to restore from a nightly backup, so a few hours of posts and comments will be missing.

Apologies again for the downtime, and for the disruption.

Oh holy cow, those servers are running at some pretty high temps!

Liquid cooling required

That's the power of optimized rust 🦀🦀

Holy fuck. I thought this was a joke before I saw who was posting it.

Do you know that you are doing to me?! I actually had to work while lemmy was down...

How does lemmy federation work in this case? Conceivably after being restored from backup the lemmy.ml instance could see those few hours of lost history as federated to other lemmy instances and resync it back as the host instance. Obv I'm vastly oversimplifiying things but what happens today?

[–] [email protected] 18 points 9 months ago (1 children)

I believe they're lost, as recieved apub content doesn't have the original post / comments, but I'm not totally sure. cc @[email protected]

It strikes me that there is the potential to use trusted remote servers as a means of recovering the lost data. I mean, nearly every lemmy instance except lemmy.ml will have copies of the missing data, and given the hugely redundant availability of that data (including the ability to compare from multiple sources to establish/verify trust), using that data to rebuild missing content seems like it could be useful functionality.

[–] [email protected] 3 points 9 months ago

If I understand, federating contents through ActivityPub only works once. Sounds a good feature to re-download contents again, but may introduce additional work as there should be some way to know if a content is missing then another job to rebuild

[–] [email protected] 3 points 9 months ago

That doesnt work because we generally cant trust remote servers. Plus we dont even know where to fetch from, so wed have to run a complete crawl of all known instances which isnt practical.

Awesome that it's back up! Thanks for all your hard work

[–] [email protected] 27 points 9 months ago

No worries, glad to hear you got it up and running again :)

[–] [email protected] 26 points 9 months ago (1 children)

No worries! Is there an announcement anywhere in case it's down? Mastodon? Matrix?

[–] [email protected] 36 points 9 months ago (2 children)

We posted in some of the lemmy matrix chats, but ya we should also use our mastodon too.

[–] [email protected] 2 points 9 months ago

it'd be helpful to post to sth like masto yeah, as its much more public facing than matrix.

[–] [email protected] 24 points 9 months ago

No apologies necessary. Y’all have been working overtime to get things back in order, and I appreciate it!

[–] [email protected] 20 points 9 months ago

When I saw LemmyMl was down I went to sleep and had a dream where I was eating extremely large fries that that were labeled on the fryholder "Sadistically Large" (chicken fries as well as potato fries) and drinking probiotic shakes so dangerous they literally had to be bundled with a free antibiotic shake by law which of course I took one sip of in front of the clerk to calm them down before guzzling the other shake down with impunity. Woke up before I found find out what the burger was. Maybe those anti-woke types are on to something.

This was, without any doubt, a prophetic dream. The apocalypse will soon be upon us! Be wary of the four horsemen: Ronald, King, Wendy, and... Chihuahua

[–] [email protected] 11 points 9 months ago

looks like some replay action too. my instance just got spanked.

[–] [email protected] 8 points 9 months ago* (last edited 9 months ago)

I saw the "502 Gateway" HTTP error message, but I never even closed my browser tab. I refreshed again today and Lemmy.ml was back online! Thanks for your hard work!

Please tell me you've been saving this picture just for this type of occasion. 😂

[–] [email protected] 4 points 9 months ago

Nope, only searched Lemmy server. 🤥

[–] [email protected] 5 points 9 months ago

Glad to see it back

[–] [email protected] 2 points 9 months ago

Remember to make regular backups, kiddos.
