We're getting reports of some people experiencing inbound call problems - either poor sound quality or one way audio. It is affecting only some calls from some networks.
Our PSTN provider is working on the problem and hopes to resolve it very shortly.
We're sorry for the inconvenience

We are still waiting for a report from the interconnect provider on the status of this fault which lies outside our network.
However we believe that it is only affecting certain number groups (eg 020 7 seems unaffected) and some networks (O2, BT and Vodafone are affected but not T-Mobile).
In the last few minutes we have seen improvements. Affected numbers are now either receiving good quality calls or the caller is receiving engaged tone.
More when we have it.

The fault is now cleared.
We'll post a report when we get one.
Thanks for your patience

We now have a report from the operator

Further to our earlier notice we are now able to give a fuller explanation of the fault.
As advised previously, we were performing preparatory work on our network last night as part of our network upgrade. All parts of the upgrade had been extensively tested within our laboratory environment, however it became apparent that one of the units that was subject to the upgrade was causing voice quality issues when subjected to our normal daytime traffic load.
We tried to identify and isolate the component as quickly as possible and were able to establish a work around to return service to normal levels. We will be taking this information back to the laboratory so we can be certain that this fault will not recur in our subsequent upgrades.
Whilst a failure of this nature is unsatisfactory at any time, we were forced to perform this work mid-week for reasons given in our earlier email and we do of course apologise for the disruption caused to our clients at such a busy time.
The total impact of this fault was limited to a maximum of 25% of the geographic areas covered and we believe the real extent of the fault to be significantly lower than that. |
