One of our MultiSite blog networks completely went of air. Nothing seems to be there anymore if you try to access it on a browser, also the login and admin page are not there.
Also in the WPMUDEV hub it disappeared, and I can't bring it back there as well.
It concerns a blog network that hasn't been used the past weeks, so we have no clue what caused this mishap. Since the blog is inaccessible, including on the hub, I cannot restore it to a previous back up.
On the hosting server, the corresponding blog directory and its content are still there. We just have no clue what's causing the problem here and need some help. It concerns: http://blogs.fasos.maastrichtuniversity.nl/logoimago/20162017/
