>I didn't notice anything yesterday either
I've a dedicated server there - it went down at 2am and came back up at just after 11am.
I rang support at 2.30am, got through immediately but was told there would be no-one to take a look until about 6am - which tallied with the fact that the IONOS service status wasn't undated until 6.50am.
Definitely a drop in support service though - last time I had an issue at this time of day (a dead disk dropping out of an array) someone was throwing in a new one within about 30 mins.
