> The maintenance work will affect only customers connected to
> ISPnet with Verizon T1 data circuits.  Customers with other
> types of connections (T3, Ethernet, etc.) including all
> customers at colocation centers, will not be affected.

> ISPnet customer Verizon-T1s are presented to ISPnet as
> channels on T3 circuits.  We are working with Verizon to
> reengineer the way these T3s are delivered to ISPnet.

> Verizon has scheduled this work for just after midnight,
> next Thursday morning.  We are allowing a 3-hour window for
> the work, as a precaution against unexpected difficulties.
> We hope that the actual customer impact will be much less,
> e.g., one or two 5-15min service interruptions during the
> window.

> T1 customers who are dual-homed with another ISP should see
> only brief periods of routing instability during the service
> window.

> ISPnet T1 customers with a backup path to ISPnet over either
> a DSL or cable-modem connection should also see only brief
> periods of routing instability during the window.

> We have also been warned that, while Verizon is currently on
> schedule to do the work on July 16, due to the complexity of
> their preparations, there is a chance that they may notify
> us that they will need to delay.  If so, we will pass on
> that info as we get it.  However, we wanted to post this
> notice now, to give our customers as much warning as
> possible.

> As always, we will do our best to limit the impact of this
> work and apologize in advance for any inconvenience caused.
