***************************************************************************************************************************************************************************


Please be advised of the following maintenance window scheduled on 24th January 2015 to IP Voice Services

Date: Saturday, 24th January 2015
Start time: 02:00 GMT
End time: 05:00 GMT

Purpose:

The Engineering Team will be performing works to migrate a portion of traffic from one Session Border Controller (SBC) cluster to another to offer increased capacity between 0200 on 24/01/2015 and 0500 on 24/01/2015.

Services affected:

IP Voice Services.

These works will ONLY affect registering SIP Gateways and SIP enabled PBX's using the uk.ic.sipconnect.hipcom.co.uk/sipconnect.hipcom.co.uk (85.119.63.4) proxy.

Impact:

Due to the nature of the works there will be a short period where affected devices, until they re-register on the new cluster, will be unable to make or receive calls. For standard configurations it is expected that this period will be no longer than 5 minutes.

The Engineering team will be working to ensure that the affect on service is as minimal as possible during this low traffic period.

The Engineering Team will be closely monitoring all systems and services, as well as the above, to ensure any disruption is as brief as possible if experienced.

[Core Network] Service Alert 19th November 2014 - Update 1
Posted by David Croft on 19 November 2014 10:45 PM
This is an incident notification regarding Internet connectivity.

Date: Wednesday, 19th November 2014
Start time: 14:50 GMT
End time: 22:00 GMT

Services affected:

Internet access.

Summary:

The LONAP peering exchange experienced issues which had a knock-on
effect on Internet connectivity across UK ISPs. We resolved the issue
at the time by disabling our connections to LONAP, and have now
restored them.

Report:

Due to an instability on the LONAP peering exchange causing packet
loss and dropped sessions, we shut down our connections in order to
reduce the impact to our customers.

Traffic was routed via resilient alternate peering and transit routes
and no further packet loss occurred.

At 15:35 we were informed by LONAP that the issue was a result of high
CPU across all switches caused by a large volume of multicast traffic
from a reseller member port. The port was shut down and continues to
be shut down until the member has demonstrated that they have resolved
their issue. LONAP is continuing to investigate why port-security did
not automatically shut down the affected port, however the exchange
has been stable since that time.

As it is our policy not to make non-emergency engineering changes
during working hours, we did not re-establish our connections until
22:00 GMT. We are observing no continuing problems, although we will
continue to monitor carefully.

This is the final update.
