Yah as mentioned by others, lots of chatter on the outages list. In short, starting at 17:47 utc level3 started leaking a whole bunch of more specifics, mainly for various comcast ASns but also others like for example AS10481 (Argentina) Many of these more specific announcements for large network such as comcast were picked up by other large network such at Tata, NTT, Liberty Global (UPC) and as a result caused a major traffic shift, resulting in a choke point somewhere along the way. One an example is the prefix 98.242.128.0/17 which is normally not visible, only as the larger block 98.192.0.0/10 (AS7922). Yesterday it was visible as 98.242.128.0/17 originated via another comcast AS (20214), with transit via level3. Good replay and visual of the timeline here: https://stat.ripe.net/widget/bgplay#w.resource=98.242.128.0%2F17 Cheers Andree My secret spy satellite informs me that Miles Fidelman wrote On 2017-11-06, 6:45 PM:
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?
