Re: MCI and SprintLink are partitioned (fwd)

Enke,

        I'd like to point out that the message below was sent
to Westnet sites (Gordon Cook forwarded it to NANOG without taking
the context into consideration).  From our perspective SprintLink 
and MCI were in fact partitioned.  My customers probably don't care 
that other SprintLink sites could get to MCI customers (except in
the "gee this Internet thing is good for the world" sort of way).  

        Last night about 7pm Mountain time we lost connectivitiy from
one of our monitoring stations to all our "SprintLink only" sites.  This
monitoring station uses MCI as it's NSP.  After doing some traces it
was pretty clear that MCI was blackholing traffic that came from the
Denver MCI POP headed to SprintLink sites.  It was bouncing around 
between MCI's SF nodes.  The MCI NOC was in fact aware of the problem
and told me it was at escalation level 4.  I was told this morning
by the MCI NOC that MCI had an "SSE hang on a border router" and that
a reset had fixed the problem.  MCI ticket #2778.

        We regained connectivity at about 7:30pm, so it lasted just
under half an hour for us.

        I doubt the nanog list is the place for this though.

Hi, 
Currently MCI peers with Sprintlink at four places: Mae-East,
Mae-West, New York NAP, and Chicago NAP, and these peers do 
backup each other.  I just checked the peer status a few 
minutes ago.  Here is what I found: 

interconnect   up time
Mae-East       6:06:45    (sheduled maintainence this morning)
Mae-West       3d04
NY NAP         4d20
Chicago NAP    1w6d

Clearly this data does not support the remark that a 
partition (total loss of peers) happened between MCI and 
Sprint yesterday evening.

Anyone willing to say what happened?

      MCI and SprintLink are disconnected at the moment.  MCI is
having a BGP problem with SprintLink.  Currently the two networks 
are partitioned.  The problem started just after 7pm (Mountain time)
and is still occuring.
