[ispnet-announce] Maintenance announcement: Saturday, Nov 4, 08:30-09:30 Eastern

[Bob Tinkelman]

On Saturday morning (Nov 4, 08:30-09:30 ET) Telehouse will be performing
maintenance that will involve it shutting down one of the two power feeds
to each of the ISPnet cabinets at 85 Tenth Ave, New York, NY, the location
of ISPnet's nycsnyoo.ispnet.net POP.

Each cabinet has power from two circuits that are connected to an Automatic
Transfer Switch (ATS) designed to continue providing power to the equipment
in the cabinet as long os good power is being received on either of its
input circuits.

If all the ATSes work as designed, there will be no interruption to any
customer traffic.

If an ATS does not, then some or all the equipment in the associated
cabinet may reboot.

If you are an ISPnet customer and if a problem occurs, the effects will
vary depending on how your service is provided.

If you have equipment located at one of ISPnet's other POPs, or if your
service is provided via a data circuit to one of ISPnet's other POPs, then
at most you should see a brief period of routing instability as routing
from your POP to the rest of the Internet adjusts to use different paths.

If you have equipment located in an ISPnet-provided cabinet at 85 Tenth,
then your equipment may reboot.

If your service is provided through the nycsnyoo.ispnet.net POP at 85 Tenth
(either via a data circuit or a local cross-connect) then there could be a
service interruption if your connection is terminated on an ISPnet switch
that reboots.  We'd estimate that any such service interruptions would last
at most 10-15 minutes.

ISPnet and Telehouse will have staff on-site to address any problems that
may arise.

Please contact ISPnet if you have any questions or requests for assistance
in preparation for Saturday's scheduled work.
