Today, like the past few days, we have had some downtime. Apparently some script kids are enjoying themselves by targeting our server (and others). Sorry for the inconvenience.

Most of these 'attacks' are targeted at the database, but some are more ddos-like and can be mitigated by using a CDN. Some other Lemmy servers are using Cloudflare, so we know that works. Therefore we have chosen Cloudflare as CDN / DDOS protection platform for now. We will look into other options, but we needed something to be implemented asap.

For the other attacks, we are using them to investigate and implement measures like rate limiting etc.

It went down again, lol. For like an hour or so, right after I claimed it was working for me. Go figure. :B

I wonder now with the semi-adversarial/semi-cooperative nature between lemmy instances, if wer'e not going to see more DDOS and other types of raids happening because a different instance has an ax to grind against yours. Say between you defederated them, or they consider your instance too big etc.

I joined July 1 for obvious reasons, I love it here.

I'm asking how many times has lemmy had to deal with these kinds of attacks prior to the "Date shall not be named"

Cause it kinda seems pretty coincidental for the amount of times I've been forced to be "offline" on this platform is gd laughable.

I thumbs up good content always.

Hmmm, we're getting a fuckload of web requests on our Lemmy too... I think I'll enable CloudFlare too! :)

Is it just me, or is old.lemmy.world still using its old IP address?

lemmy.world and m.lemmy.world

old.lemmy.world should be cloudflared, too

[–] ruud@lemmy.world 8 points 1 year ago

Yeah we will fix that soon

[–] irotsoma@lemmy.world 9 points 1 year ago

Yeah, this is just growing pains for any website. Get popular enough for it to be "fun" to target. Then get enough data that it's "profitable" to target. Etc. And the usual way to deal is to first use an external solution at least until it becomes too expensive due to traffic volume. Then make your own solutions for problems you can solve yourself and pay external companies for the ones you can't.

[–] ruud@lemmy.world 8 points 1 year ago

Yeah, first make sure it doesn't show anywhere anymore

[–] cantevencode@lemmy.world 8 points 1 year ago (6 children)

You should change the public IP of the server if you haven't already

Not sure if it’s related, but today on Mastodon, I’m unable to upload photos. Also can’t see pics from other users. Profile pics are mostly greyed out too.

[–] Noneo@lemmy.world 8 points 1 year ago (6 children)

Obviously cloudflares ddosing lemmy just to get some extra money

Thanks a lot for all the work you folks are doing to keep this instance up.

[–] Kovu@lemmy.world 7 points 1 year ago* (last edited 1 year ago)

thank you guys for your work! is it possible to disable the cloudflare analytics/telemetry aka cloudflareinsights?

[–] md5crypto@lemmy.world 7 points 1 year ago

Also when will CloudFlare drop lemmy as a 'Nazi' site?

[–] orangeNgreen@lemmy.world 7 points 1 year ago

Thank you for the update!

[–] Killgannon@lemmy.world 6 points 1 year ago

Nice try, Mr. Huffman.

[–] AphoticDev@lemmy.dbzer0.com 6 points 1 year ago (1 children)

It's not ideal, but there's not a whole lot of options out there for DDoS mitigation.

Do you run a reverse proxy infront? Eg. nginx is pretty performant at dropping unwanted traffic.
