UPDATE: MFS Outage: 6:30PM PDT 4/18/97

This update is being sent at 12:07AM 4/19/97:


Starting at approximately 6:30PM PDT, MFS's power
unit on their fiber mux located at the Digital Internet
Exchange is resetting every 30 seconds to 1 minute.

All MFS fiber facilities are down during the power
reset. This includes all MFS/Worldcom DS3 and T1
circuits entering the PAIX collocate facility.

The IX Operations staff (Digital Internet Exchange
Operations) believes that the problem is due to a
bad rectifier on the fiber mux's power rack.

We are currently waiting for MFS to provide a dispatch
to fix this problem.


At approximately 7:30PM, MFS arrived on site.
We offered them clean power from our in-house
UPS and rectifiers at this time, which would have
prevented the rapid, regular resetting of their
line cards. They were not interested in the power
at this time.

By 8:30PM, they were convinced their rectifier
was the cause of their power loss. They still are
not interested in our power.

By 10:15, they had restored power to their rectifier.
Many of their line cards, including an OC48, did not
return back to an operational state, likely due to
the rapid resetting previously. Again we offered our
power, however now they definitely were convinced it
was unnecessary as their rectifiers were functioning.
Instead, they are forcing us to wait until next week.

As of 11:00, the line cards are still not functioning.

UPDATE: 12:10AM 4/19/97

As of 11:45PM, the MFS technicians decided to go
ahead and begin cut over to our power so that at
least the power is stable while they work on the
line cards. They are currently working on this cutover.

More updates to follow, as soon as available.
