[ale] Slightly OT: AT&T Fiber upload failures.

[neal at mnopltd.com]

Thanks for the pointer.  I understood the AT&T Business Fiber SLA to be 
37ms max latency.   We have typically seen 200, and sometimes over 500.

Thus far I haven't gotten past level 2 tech in Bangalore.    AT&T 
managers are avoiding me; perhaps just blocking me.

That's kinda why I wanted to figure out how to apply for a credit on our 
bill due to them not meeting the SLA.  Figured that MIGHT get someone's 
attention on this continent.
