TMG Crashes Since June 28

As I was getting ready for work on Thursday morning, I got an email that websites published through Microsoft Threat Management Gateway (TMG) were unavailable.   Kind of a mystery, but nothing recurring so I restarted the services and moved on.

Today, via the Microsoft TMG blog, I read that this occurred to many people the morning of June 28th.  They report that rollup 2 for TMG 2010 sp2 fixes this issue.
