>> Folks,
>>
>> It seems like various media outlets are reporting a "major Internet
>> outage" - some going so far as to call it an "attack."
>>
>> A few headlines that crossed Facebook today:
>>
>> "Major internet outage hits the U.S."  (Mashable via AOL News)
>>
>> "Widespread Comcast internet outage across U.S. includes 
>> Massachusetts
>> customers"  (WHDH, Channel 7 News, Boston)
>>
>> A couple of more detailed sources reported that issues at L3 were
>> effecting Comcast, specifically.
>>
>> Kind of interesting that there's been no mention here on nanog, nor 
>> have
>> I personally noticed any issues (as a user or a hosting provider).
>>
>> Tempest in a teapot?
