There have been a few reports of this. It seems to come and go across the NY metro area, beginning around 6/11. The culprit appears to be at or near one of the routers known as "verizon.com.customer.alter.net" - 159.179.110.202, 152.179.7.8.154 and possibly other addresses depending on peer. Private peerings seem to take different paths and often aren't impacted. At a regular pattern, but on an interval that's changed a few times over the past few days, this router will drop about 10% of packets traversing it for almost exactly 1 full minute. The interval between these failures has varied from 10 to 30 minutes over the past few days but it seems to always be a multiple of 10 minutes. The pattern is really visually impressive if you graph it out and I'd actually be curious to know how they managed to make it happen (I've been musing about error thresholds and hold-down timers and...etc. but who knows really).
