When it happened on January 7 I opened a support call and was referred to ebays status page which showed some things that really didn't explain what happened. I was also told that sometimes on the hour ebays servers slow down. At 2AM? I wasn't offered any suggestions on what to do.
Then it happened on January 9th and then on January 10th. 4 auctions with no bid even attempted. It can't just be lag with a 45 second lead time bid not even submitted. If it takes more time than that then something is just plain malfunctioning.
