I got this yesterday I think - FYI - sigh:
Dear IS Customer
Internet Solutions has two STM1 satellite circuits that terminate on antenna RCK-01A at the Roaring Creek (Pennsylvania, USA) Earth Station. Our vendor, AT&T, has a requirement to make adjustments to the Antenna Tracking System. In order to complete this task, the two circuits need to be temporarily migrated to a second antenna (RCK-02A). These adjustments will enhance the stability and tracking ability of the antenna.
We intend on migrating one STM1 circuit at a time, to minimise the impact on our customers. The migration will result in the circuit being down intermittently during the maintenance, and traffic will be rerouted.
The first STM1 move is scheduled for:
Friday night, the 6th October 2006 at 22h00 (SAST), through to Saturday morning, the 7th October 2006 at 08h00 (SAST).
We will then go through a period of monitoring the first circuit for 14 hours after which we will commence with the migration of the second STM1.
The second STM1 move is scheduled for:
Saturday night, the 7th October 2006 at 22h00 (SAST), through to Sunday morning, the 8th October 2006 at 08h00 (SAST).
This will result in intermittent degradation of International access services for ADSL and 6-to-1 Access customers during the maintenance.
General internet browsing to some international sites may also be affected, as traffic to two of our cache servers (one cache at a time), may be interrupted.
Please do not hesitate to contact either your IS account manager or the relevant service representative should you require further information or the IS GSC on +27(0)11 - 575 0055.
Regards
The IS Ops Team.
