[Comtec Announce] [Core Network] Maintenance window 13th July 2014

[David Croft]

Please be advised of the following maintenance window scheduled on our network:

Date: Sunday, 13th July 2014
Start time: 10:00 BST (UTC+0100)
End time: 14:00 BST (UTC+0100)

Purpose:

We will be performing software upgrades on our distribution switches at Reigate.

Services affected:

All services hosted in Comtec House, Reigate (LSREI01).

Impact:

Low.

The redundant pair of distribution switches will be upgraded one at a
time. Customers who have connected to both distribution switches per
our recommendations will observe no operational impact as they will
fail over to the redundant switch while the other is being upgraded.

Customers who are single-homed to our network will observe a period of
downtime of 5-15 minutes during this window. In the event that
roll-back is required, there will be a further interruption while the
original software is restored.

No outage is anticipated due to the resilient nature of our network
and transport out of Reigate, however services are "at-risk" during
this window. IP voice services will be unaffected.

Comtec NOC is tracking this issue under ticket [#GZO-670-71256].

Regards,

David Croft
