Apologies, the problem was on our side. There was no attack.
We had a partition running full (causing a crash) , we had a serious backlog on updates, + several other nastiness. I have not been involved in this for years now and it was quite a challenge.
Current status is everything is updated and fixed on the server side. However, the hardware is a bit dated. We will thus migrate to new hardware this year which will cause some more outage. However, this will be planned and announced.
Feel free to contact me by PM, we have set up means to communicate in case we should go offline unexpectedly again.
My sincere apologies to you for not communicating this sooner.
