Cisco ASA 5510 Clientless SSL VPN - OWA Extremely Slow

medi911 asked
Over the past two days I have had several users complaining that accessing OWA over our Cisco ASA 5510 Clientless SSL VPN has become unbearably slow.  I confirmed this by downloading a 700kb attachment and it took almost 5 minutes.

I have not changed any settings on my ASA.  I'm perplexed as to what could have caused this.

Microsoft pushed a bunch of updates this past Tuesday...
Since nothing changed on the ASA, nothing changed at the ISP (or did it??)
What changed? Updates! It would not be the first time that Windows updates broke something.
Turned out the problem was the ISP.
