Since 7:30AM CDT Friday morning, we've seen strange problems across L3 where around 1-2% of traffic flows are dying. It is interesting behavior in that new flows from the same source to the same destination work, however, in the cases where the traffic is stopped we never receive the SYN-ACK nor any of the retransmits. The destination side continues to receive the SYN retransmits. On Wed, Jul 29, 2015 at 6:52 AM, Robert Blayzor via NANOG <nanog@nanog.org> wrote:

Is anyone seeing packet loss or routing issues on the Level3 network on
the east coast right now?
We’ve seen a slew of problems going west out of Level3 in NYC the last couple of nights. Last night was particularly bad to the point we had to shut our Level3 BGP sessions down to route around the issue.
