We got bit by this overnight.

Customers transiting our network on the west coast of North America may 
have experienced Latency and Packet Loss. This was due to a fiber cut in 
our vendors network around the Los Angeles area. The vendor has found 
the damaged fiber and have repaired the cables. Cogent NOC is now 
monitoring this event. Customers should have seen their services 
restored at 11:46 AM ET. The master case is HD303782528.

Oh, ok. That explains why it stops in Lax within Cogent. It
appears to be a submarine cable cut from their page:

Customers Transiting our network from Europe to our Asian markets may
be experiencing Latency and Packet Loss. Multiple vessels are
currently being gathered and/or being dispatched to carry out the
repair operations from the submarine faults currently being reported.
There is NO ETR at this time.
