Planned works: outage notifation:
Posted on September 18th 2009 - 11:34 by chris
Maintenance Window: Monday 21st October 2009: 04:00 to 05:30
We will be carrying out essential maintenance to one of our virtualisation servers which is currently showing network performance issues. We will be migrating the virtual servers hosted on this machine to alternative hardware in order to take the host machine out of service.
Exepected disruption. Incoming PSTN calls will be blocked for an estimated period of two minutes during the change window.
It is also possible that some customers may have difficulty dialling out during this maintenance window however it is envisaged that disruption will be minimal.

21CN connectivty issues in 0207 and 0208
Posted on Tue, 8 Sep 2009 10:37:10 +0100 by chris
We've been made aware that this morning some users connecting to us via ADSL2 from the 0207/0208 London area codes are experieincing rapid disconnections on their ADSL service, remaining on-line for no longer than a couple of minutes.
If you are affected by this we recommend consulting your ISP.

Initial IPv6 support
Posted on Tue, 2 Dec 2008 13:21:12 +0000 by theo
Over the last week we have been adding IPv6 support to our network, servers, and services. Today we have added support to some of our infrastructure, namely the following 2 sites:
Additionally we have also enabled IPv6 on our authoritative name servers:
a.ns.voip.co.uk 2a02:68:2:1001::d001 b.ns.voip.co.uk 2a02:68:2:2001::d001 However we have initially only added glue for a.ns. We will add the glue for the b.ns in a few days.
We are working on adding IPv6 support to our SIP and media platform, and expect to see native support in the near future.
Please direct any problems with IPv6 services to ipv6@voip.co.uk.
We would love to hear from any vendors that would like to perform interop testing over native IPv6.
Additionally, any service providers on LoNAP or LINX that would like to peer native IPv6 with us (via AS21396) should also contact ipv6@voip.co.uk.
At VoIP.co.uk, we're commited to fully deploying IPv6 on our netowrk and platform - We believe that the universal deployment of IPv6 is vital for the long term, widespread deployment of SIP over the coming years, not to mention the entire internet!

IPv6 SIP support
Posted on Fri, 5 Dec 2008 02:08:31 +0000 by theo
As previously mentioned, we have been adding IPv6 support to our network. Today, we have added support for making calls over IPv6 through our platform, and have deployed to our test platform for customers to trial. To make calls over IPv6, use test.voip.co.uk instead of your normal platform. There is currently only support for INVITE dialogs; REGISTER methods will not be processed. We are working on fixing this, and hope to provide an update soon. As with any other IPv6 related issues, please report them to ipv6@voip.co.uk.

Inbound PSTN issues
Posted on Fri, 4 Jul 2008 12:48:53 +0100 by theo
We've been seeing intermittent call failures on inbound calls from the PSTN to our network. We have tracked this down to a faulty line card, and have shut-down the affected ports. Calls are now flowing normally again.

Outgoing PSTN calls (update)
Posted on Thu, 26 Jun 2008 12:41:21 +0100 by theo
The issue that caused us to take the PSTN gateway we took out of service this morning has been tracked down to a misconfiguration on a dial-peer on the gateway having problems. It has been now been put back into service and we are closely monitoring calls.
No calls will have been affected since it was taken out of service, however this morning a number of outbound calls (from 9:33 until 9:38) hitting that gateway from the B platform will have received a 'network busy' response. Re-dialling may have caused the call to go through, as it was down to random gateway selection if this error was received.
The failover testing we're been trialing on the beta platform has gone extremely well, and the results have been so far perfect in eliminating PSTN gateway issues we've started to see as we add more and more PSTN interconnects. We will schedule some maintenance work over the next few days to put the same functionality on the B platform, which will stop future unforeseen problems like this affected any calls at all.

Outgoing PSTN calls
Posted on Thu, 26 Jun 2008 09:38:56 +0100 by theo
we are investigating a PSTN gateway that was causing problems this morning rejecting outgoing calls.
The gateway has been removed from service and is being investigated.

[MW-0806-03] controlled PSTN failover tests
Posted on Sat, 21 Jun 2008 14:52:20 +0100 by theo
MAINTENANCE WINDOW NOTIFICATION
At risk Window Commences: 2008-06-26 03:00:00 BST (UTC +0100)
At risk Window Concludes: 2008-06-26 04:00:00 BST (UTC +0100)
Reason for notification: Controlled testing of PSTN gateway failure failover
During the above maintenance window, we will be performing simulated hardware, software, and network failures to ensure that PSTN calls fail over successfully and are not adversely affected by platform component failure.
This work will involve disabling parts of the platform in a controlled manner, and ensuring traffic flows correctly through alternate gateways. We will then re-enable the disabled parts, while ensuring throughout that traffic is not affected.
It is hoped there will be no downtime at all, however the very nature of the work means that there is an increased risk of outgoing call failures.
The network will be closely monitored by engineers during and over the hours following this maintenance. As always, if you have any problems outside of this window please contact us through your normal support channel.
An all clear notification reporting results of maintenance will be issued on conclusion. Should you be suffering any loss of service after this time, or outside this maintenance window, please get in touch as soon as possible.
Contingency plan:
Should the above testing fail to be successful as planned then the network will be restored to its prior state for analysis of redundancy failure.

[MW-0806-01]: Altered to 2008-06-26 0100 - 0500
Posted on Sat, 21 Jun 2008 02:15:20 +0100 by theo
We've needed to change this maintenance window by a few days in order to ensure platform stability.
This work will now take place between 0100 and 0500 on Thursday the 26th of this month.

billing issues 2008-06-19
Posted on Fri, 20 Jun 2008 17:06:05 +0100 by theo
We've recently noticed a side effect of yesterdays PSTN gateway problems meant that anyone who was on a call on the B cluster (proxy.voip.co.uk) at a number of points in the morning may not have seen their call get cut of from a billing perspective. This resulted in those specific calls being either over or under charged.
The problem has been tracked down to a signalling node that isn't clearing billing information down correctly under a certain failure scenario, of which yesterday was the first time such a scenario happened. A fix has been put into the stack already, and this will be rolled out over the weekend onto the live platform.
We will of course refund anyone who was adversely affected by this over the weekend. The process will be automatic as we have safeguards in place to ensure we can retrospectively correlate billing information in situations like this and re-generate the call records, however should you notice it because it's affected your ability to make calls, please contact support and we'll credit your account temporarily until the call is re-rated at the correct amount.
An update will be posted here as soon as there is further information.
