Oof, sorry you are dealing with that load. Beyond blocklists, caching tiles plus aggressive rate limits per ASN, and serving 429s with Retry-After can help. For bulk use, requiring API keys for heavy endpoints can also cut abuse. Thanks for keeping OSM running.

@osm_tech Ugh, I am so sorry to hear this, and thank you to everyone working on this project.

Such a nightmare, and so completely pointless. 🤬

[pesasa@mastodon.social]

@ISibboI @osm_tech I think, that spreading it on 100 000+ IP addresses tells they know they are doing shady thing.

Time to deploy Anubis in front of all the URLs that the scrapers are hitting.

[tomchadwin@en.osm.town]

@osm_tech Good luck, and thank you as always.

[don_clemente@chaos.social]

@osm_tech wonder if it is collateral damage or intended, to get rid of alternative sources of information?
Anyway, zip-bomb the hell out of them.

[osm_tech@en.osm.town]

@Don_Clemente Just dumb scrapers. They want our data, so maybe we /should/ redirect them to the latest full history planet file, it is only 245GB

[osm_tech@en.osm.town]

@gme Anubis is great, but not ideal for us. We have reasonable technical mitigations in place, but it is unfortunately an arms race (and time/resource blackhole)

[don_clemente@chaos.social]

@osm_tech yes, but that's heavy on your resources and bandwidth. A zip file of 10GB Zeros is much more resource-efficient on your side

@pesasa @ISibboI @osm_tech It's a pattern I've seen others relate to the building of AI datasets.

@pesasa @ISibboI @osm_tech
If its helpful (if you want to stuff something unpleasant down their throats), I believe @jwz has been making a 'json bomb' for (AIUI) pretty much this purpose:
