Bad gate
I have just experienced a rather strange outage in the Illustrator forum: I made a reply and submitted it, but nothing happened for a long time. Eventually, the reply was replaced by a small box with the message Bad gate. At the same time, the Illustrator forum (open in another Tab) was replaced by the Site temporarily unavailable message.
After maybe a quarter of an hour (trying now and again), the forum reappeared, but I was logged out. I had to login and close the tab with the Bad gate. When I entered the thread in question from the forum to rereply, I was able to use a recovered version.
Stay away from bad gates, if you can spot them.
