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.

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

lemmy.world and m.lemmy.world

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

[–] Nerrad@lemmy.world 11 points 2 years ago

My biggest problem with CloudFlare is that very often they don't play nicely with VPN.

[–] HelloHotel@lemmy.world 10 points 2 years ago* (last edited 2 years ago) (9 children)

Whats the motivation to DDOS? How mutch is specific malice to lemmy or lemmy.world itself and how much is genaric.

Nice try, Mr. Huffman.

[–] Obstagoon@lemmy.world 10 points 2 years ago

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

[–] ruud@lemmy.world 10 points 2 years ago

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

[–] ryannathans@lemmy.world 10 points 2 years ago (5 children)

I assume you are rotating ip addresses after swapping to cloudflare?

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.

Script Kiddies are definetely some of the saddest people on the internet. If you're gonna be an unethical hacker at all, actually do it. Don't be a sissy.

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.

[–] Kovu@lemmy.world 8 points 2 years ago* (last edited 2 years ago)

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

[–] kratoz29@lemmy.world 8 points 2 years ago (2 children)

What solution were you using before Cloudflare?
