Our matrix server went offline after a huge spike in memory usage occurred. This seem to affect more servers in the matrix network and the origins of that aren't clear yet. We've restarted the server this morning, and at this moment our server is catching up with the network.
We will monitor the situation and see whether it was a single incident or something of a re-occurring nature.
Until the problem is resolved, we will keep the status as "investigating" and the component as "Partial outage".
