IMPORTANT: Exchange Server 2010 Hotfix For DAG Spanning Multiple Datacenters

Author by Matt Sims

I recently encountered an issue at a client where their Exchange Server 2010 Database Availability Group, which spans two datacenters, would fail [all databases would end up dismounted] when the WAN link connecting the sites saturated.  The simple fix was to heed the Exchange product team's advice and apply a hotfix written to address issues like this.  Please see below for a link to the EHLO blog post announcing the fix.
