[Comtec Announce] [Core Network] EMERGENCY Maintenance window 10th July 2018

[David Croft]

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

Start date: Tuesday, 10th July 2018
Start time: 22:00 BST (UTC+0100)
End time: 04:00 BST (UTC+0100) Wednesday

Purpose:

Our emergency engineering works this past weekend were successful with
one exception: one router could not be replaced due to an
incompatibility with our long range fibre SFPs. The original router
was therefore returned to service. This incompatibility was not
detected during testing as the lab links were short range.

This maintenance window is to attempt the router replacement again
with new optics that are arriving tomorrow. Replacement optics will be
installed and the new replacement router brought into service after
testing.

Services affected:

Cloud Ethernet customers single-homed out of Interxion LON1 (CLBIS02).

Impact:

HIGH - Customers with a single connection to our Interxion LON1
(CLBIS02) PoP will experience an interruption in service while the
device is replaced.

Please note: This maintenance window is being declared as EMERGENCY
without the normal notice period due to the need to perform this work
urgently in order to prevent a recurrence of the outage of 22nd May.

Regards,

David Croft
