ISPnet scheduled maintenance, Staten Island POP, Wed, June 13 - precautionary announcement

[ISPnet NOC]

Quick follow-up and clarification:

   The announced maintenance window affects only those ISPnet
   customers with equipment at the Telehouse colocation center
   at 7 Teleport Drive, Staten Island.

This should have been stated more clearly in the original posting.





> ISPnet has scheduled a maintenance window for Wednesday night,
> June 13, 22:00-23:59 EDT.

> During this window we will be reconfiguring the electrical power
> feeds in one of our cabinets.

> We expect that the work will NOT have any customer impact.

>   [The electrical circuits are connected to automatic
>    transfer switches which should continue to provide
>    the equipment in the cabinet with uninterupted power,
>    when one of the two redundant electrical circuits is
>    momentarily disconnected.]

>   [Even when one of two redundant electrical circuits is
>    temporarily disconnected, the remaining circuit is
>    both UPS and generated backed-up.]


> However, whenever dealing with this type of equipment, there is
> a small chance that a brief power hit will cause a router or a
> switch to reboot.

> If such a problem occurs, then

>    o  dual-connected or dual-homed customers may see a brief
>       period of routing instability during a transition.

>    o  single-connected customers will see a service interruption
>       of up to 10 minutes.

> We apologize in advance for any inconvenience.

> The upgrades will allow us to do a better job monitoring and
> managing electrical power usage and, thereby, help us to provide
> more reliable service to our customers.
