I'm sorry, Andy. I must have emailed the outages-condescension listserv in error. My apologies.<br>
<br>
Does anyone else have an insight about why the outage affected every one? Was AT&T's infrastructure really the source of the disruption as Andy says? If so, does this highlight a potential problem of a private company having too much control over a critical
piece of public infrastructure?<br>
<br>
...or did the equipment upgrade at the 33 Thomas Street NSA listening outpost not go as planned? :-D
