RE: Cogent leaking /32s?

We had a problem with cogent about a year ago.  Somehow.. cymru was
announcing a /32 of ours and black holing it for whatever reason.  It
was removed but wasn't happy that cogent was allowing cymru to do this
sort of action.  To this date we do not have a valid reason from cogent
on why they allowed this to happen.

Cheers,

I received an alert from Cyclops telling me a probe in AS513 had seen a 
/32 that I announce to Cogent for one of our BGP sessions.

Did anyone else see this?
