Posted on SANS this morning:

For a brief time this morning (in the US), the SSL certificate for Hotmail was broken. It gave the SSL certificate for www.gendcom.info, which seems to be a legitimate site that uses SSL. The Hotmail SSL certificate was quickly fixed. After researching, I discovered that both organizations use Savvis webhosting. So I'm thinking this was a technical glitch at Savvis.
