IMPORTANT: We're seeing a large scale attempt to bulk-register bot accounts across the public Matrix network (including captcha bypass) in order to perform spam flood attacks. If you're running a public homeserver please disable open registration, or require email for signups.
@matrix Meanwhile server admins can use delete room API to remove users from Matrix HQ and remove it's data until things settle down. Documentation for the API is at https://github.com/matrix-org/synapse/blob/develop/docs/admin_api/rooms.md#delete-room-api and Room ID for HQ is !OGEhHVWSdvArJzumhm:matrix.org
@matrix I experienced huge (~3h) delays of message delivery between me at tchncs.de and a friend at matrix.org. Perhaps it's due to this issue?..
@matrix welcome to the big leagues! Sending you all love from Libera, and all the best for working out a federated moderation strategy.
@hbenjamin @matrix It does! Just closed signups, for now

The traffic caused by these distributed spam attacks is currently causing federation delays for servers which are participating in a targeted room; we are working on a performance fix for Synapse to address this.
