[outages] Possible Cogent > CFL Brighthouse Issue?

For about the last week I've noticed remote desktop to my NOC workstation 
has just crawled.

Also noticed I could only pull ~1Mb/s from anything at the NOC.

Can anyone confirm what I'm seeing?

NOC=208.90.219.18
Home=50.89.171.242

Trace is asymmetric. Using BGP knobs to avoid AS7843>AS174(?) resolves the 
issue.

Other Possible Relevant data.
AS2828's route to AS33363 is Via AS7843. So they aren't announcing 
50.88.0.0/15 to AS2828 it seems.
Can't seem to get to AS3356's Looking glass, But I'm pretty sure AS33363 
prepends the hell out of it's routes sent to AS3356.
