[Comtec Announce] Maintenance window 12th February 2013

[David Croft]

Please be advised of the following maintenance window scheduled on our
network and those of other UK ISPs:

Date: Tuesday, 12th February 2013
Start time: 23:00 UTC
End time: 06:00 UTC

Purpose

As part of the expansion of the LONAP Internet Exchange, of which we
are member, some renumbering work is required.

Impact

Due to our redundant network connectivity and peering arrangements, we
are expecting no significant operational impact from this work.
However, routing to certain destinations may be suboptimal during this
window. The observed consequences of this may be slightly increased
latency or packet loss.

We will be performing our changes at the beginning of this maintenance
window, however there is a seven hour window for other ISPs to
complete their work. While we are hopeful that all members complete
their renumbering in a timely manner, there remains the possibility
that some members will take longer to complete, so please be warned of
possible suboptimal routing beginning on 12/2.

Please note that is not specific to Sargasso Networks and will affect
all UK and international ISPs that connect to LONAP. We will be
monitoring the migration carefully, but it will be largely out of our
hands, in the control only of those ISPs who are late to renumber.
Nevertheless, we will ensure that our critical peering partners
including our IP Voice services are not adversely affected.

Regards,

David Croft
