Yeah me too, this sucks be time for a subscription account, I'm dead in the water....
Worked fine last time and now this feature service is completely gone, I have basically a blank web map now online, management will be impressed.
Hopefully next week something miraculous will occur and I'll be able to publish my services from ArcMAP.
I tried everything, file size didn't matter, although I had to do nothing before, map analysis was clean before upload attempt....maybe its a Friday the 13th thing.
