[outages] Internap/PNAP San Francisco outage

[Rusty Hodge]

I guess the GTT/sfo002.pnap.net connection was flooded. It took them about 30 minutes to fix the issue.

``At 5:34pm ET, the Internap NOC detected an attack directed at a single
destination which caused customers in the SFO PNAP to experience sub-optimal routing and intermittent service issues. This has been resolved and all services are back up. Please contact the Internap NOC if you have any questions or concerns and refer to ticket number 1109893.``
