Ah - (selfishly) pleased to see that somebody else is having/had a problem.
As you can imagine, I log in very frequently - either from my hotel room laptop or my home office desktop.
Since arriving in the latest hotel room I have been unable to log on from my laptop - VERY long delays in loading, then ending in a "Cannot display this page".
I could, however, remotely log into my home office desktop - FROM my hotel room laptop, and then connect through the desktop with no problem.
However, yesterday, the problem went away without any comment - I just logged on directly from the hotel room.
