Yesterday, I got just "An error has occurred. Please try again later" the whole day. And I was not the only one.
Today it worked for about an hour for me (between 09:00 and 10:00 GMT+1), then it started with http-501 errors, and now this:

Update: My favourites are gone! Years of careful reading, searching and safekeeping: gone! According to the Well Known Problems I should NOT have logged on before Nov, 9th, because the updates were pending. If you did, you favourites are regarded as up-to-date, and will not be migrated. According to metaklunk2, I should have logged on. Shouldn't. Should. Sigh.
So it's like my own fault?!? Right. Don't think so. Unhappy customer here, Oracle.
