Hi,
I had to disable federation due to abuse that created heavy resource usage and outages in the recent weeks. Situation seems to be stabilised at the moment.
If you want/need some homeserver whitelisted - please comment, write a message or ping me on matrix @saint:group.lt.
In general - if you have issues with matrix - don’t be shy ;)
@saint So probably someone else of it was an attack then. Hopefully it gets patched in Synapse so it can’t happen again.
