When I first got to the computer 24 hours ago, none of the usual PPRuNe pages were available at all.
I was on the point of ringing the Prime Minister, when a second visit about 15 minutes later was rewarded with all of the usual favourites - and a profound sense of relief
. The 'blank page after posting' problem was noted shortly after that.
There may have been a more serious problem earlier on, and what we see now are the 'aftershocks'.
FWIW
