We apologise to our TalkTalk DSL customers who have suffered an outage to their service at approximately 01:50 till approximately 04:10 this morning?

We do know that it wasn’t an interconnectivity problem so we are seeking an explanation from our TalkTalk Wholesaler and will post an update when we know more.

We apologise for any inconvenience this may have caused.

Starting at approx 19:55 this evening, our main link to Amsterdam started showing high latency and packet loss. This is considerably more disruptive than a complete outage, as the auto-failover mechanisms don’t kick in.
All data is currently manually routed over the backup link. A ticket has been raised with the link supplier.

Update at 21:22 – our monitoring is showing the main link to be behaving normally once again. We will leave the maanual route override in place until we have heard from the supplier what has been done.

Update at 22:05 – An attempt to put the main link back in service was not successful, suggesting the link behaviour is changing with traffic. We remain on the backup link for now. Further investigations will continue.

We apologies for the outage, and also for the slow posting of the initial update – investigation of the problem took priority.

Update at 10:05 on 25/05/16 – The main link was successfully re-enabled at 09:30 this morning and has been behaving normally since.

The fault is believed to be with the supplier who routes traffic between our datacentre and the science park in Amsterdam. We have requested an explanation and will update this status with anything we receive.

We are aware that our link to Amsterdam had some glitches overnight which resulted in a series of short outages of a few minutes each, the back up connection kicked in automatically as intended. However, due to the outages being within minutes of each other this glitch was more noticeable due to the back up taking a minute or so to kick in each time. The link has been stable since 04:00 this morning.

We believe the cause of the glitches was down to a problem with one of our interconnectivity suppliers.

We apologise for any inconvenience this may have caused.

Update: We have received notification that the connectivity provider in question is changing a switch.

At around 14:15 there appears to have been an issue with a connectivity provider in Telehouse that affected DSL connections and some routes between our data centres.

The issue appears to have been resolved and customers already have or should see their connection restored.

We will post an update when we are aware of the cause.

We apologise to those customers affected.
