There were 16 Matrix outages since June 20, 2025 totaling 461h 5m of downtime. Each is summarised below — incident details, duration, and resolution information.
Around 07:00 UTC until 08:00 UTC, performance on the matrix.org homeserver was degraded due to a transient problem preventing database maintenance.
We are investigating a problem sending messages via the matrix.org homeserver
The problem was related to an upgrade to the homeserver on matrix.org. We have rolled back to the previous release, and service has been restored.
The homeserver has been stable since rolling back. The Synapse team will work on a resolution to the bug that caused the outage.
Outbound federation from matrix.org paused for several minutes, and is now catching up.
This incident has been resolved.
We are currently investigating this issue.
A fix has been implemented and we are monitoring the results.
This incident has been resolved.
Performance on matrix.org is currently slow due to ongoing device cleanup.

We are currently investigating this issue.
The degraded performance was linked to a harmless error which nevertheless was being reported millions of times per hour, affecting CPU. We've fixed the error and service appears to be stabilising.
This incident has been resolved.
We've identified an issue with the matrix.org database
We are in the process of restoring the matrix.org database from a backup. The matrix.org homeserver will be offline until this has been completed
Restoration is ongoing, we do not yet have a concrete estimate for resolution. Live updates here https://bsky.app/profile/matrix.org/post/3lxuslbzjuc2t
The database has been restore, and verification checks complete. matrix.org's Synapse has been started up again and we are monitoring
We are continuing to monitor for any further issues.
This incident has been resolved.
We are investigating continued problems with inbound federation on the matrix.org homeserver
We are continuing to investigate this issue.
A fix has been implemented and we are monitoring the results.
This incident has been resolved.
matrix.org inbound federation was inoperable from roughly 18:55 UTC to 20:00 UTC due to a logic error during a code roll out. The issue is now resolved.
We're investigating reports of broken functionality in federated and unfederated rooms that contain matrix.org users. As a workaround, one can create a new room and continue communicating there. We are working to identify the cause and correct the affected rooms.
We are still working to determine the root cause, which currently appears to only originate on the matrix.org homeserver. In the meantime, we've devised a fix and will be attempting that shortly.
We are still working to restore all affected rooms
We believe we have restored the majority of the affected rooms. We are working on verifying and identifying any remaining rooms that may have been affected.
We believe that all of the affected rooms have been fixed.
We are currently investigating this issue.
The issue is due to degraded DB performance. We've identified what's slowing the DB down and cleaning it up.
A fix has been implemented and we are monitoring the results.
This incident has been resolved.
