Status update: we’re 47TB through restoring the 55TB db snapshot of the matrix.org DB, but then have to rebuild the DB and replay the subsequent 17h of DB traffic, which will take several hours. Thank you for your patience, and apologies once again for the outage.

Status update: we've restored the 55TB snapshot and subsequent incremental backups, and are about to replay the remaining traffic since the backup. There are still several unknowns, but if things go well the matrix.org instance should be back in 3-4 hours.

the matrix.org homeserver is having problems: https://status.matrix.org/incidents/mm9hdm78svgv apologies for the inconvenience…

So: the matrix.org database secondary lost its FS due to a RAID failure earlier today (11:17 UTC). Then, we lost the primary at 17:26. We're trying to restore the primary DB FS (which could be fastish), while also doing a point-in-time backup restore from last night (which takes >10h). We believe the incremental DB traffic since last night is intact however. Apologies for the downtime; folks on their own homeserver are of course not impacted.

Sorry, but it's bad news: we haven't been able to restore the DB primary filesystem to a state we're confident in running as a primary (especially given our experiences with slow-burning postgres db corruption). So we're having to do a full 55TB DB snapshot restore from last night, which will take >10h to recover the data, and then >4h to actually restore, and then >3h to catch up on missing traffic. Huge apologies for the outage. Again, folks using their own homeservers are not impacted.

We’ve now published the details of the security issues which we addressed in Monday’s coordinated security release of Matrix: read all about Project Hydra at https://matrix.org/blog/2025/08/project-hydra-improving-state-res/ and please upgrade your servers and rooms where applicable.

We issued a security release to fix two high severity protocol vulnerabilities. Please upgrade your servers and clients.

Our checklist and useful links in the blog post below

IMPORTANT: We're pre-disclosing two high severity CVEs in Matrix's federation protocol, which will require a coordinated upgrade on July 22nd of all servers running in untrusted federations. Client developers may need to make minor changes too. Please see https://matrix.org/blog/2025/07/security-predisclosure/

Project Aurora, the EU adopting Matrix for cybersecurity crisis management, and significant improvements in the rust SDK thanks to DINUM's HackDays.

@thanius Just a namespace collision, unrelated to the Matrix protocol as far as we can tell. We're staying tuned.
