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).
