UPDATE: Broadband packet loss & intermittent connectivity

UPDATE:

We have seen the services starting to recover and our normal traffic profile is virtually back to normal. Any subscribers still to reconnect may require a router reboot if the issue persists.

The fault is still open with our supplier until the overall service has been restored. Our apologies again to those affected.

One of our back-haul providers is aware of an ongoing issue affecting a small section of our lines which is causing either packet loss or intermittent connectivity or sometimes both. NOTE: This isn’t affecting all lines but the following STD codes are those seeing issues through this supplier. We expect an update by 14.30. In the meantime, we apologise if your line is one of those affected.

Supplier upgrade work affecting a few DSL circuits 29/8/17

One of our carriers is performing some planned works on their interconnect in Telehouse North. We have resilient interconnects in other locations, however during the work you may see your connections drop and re-connect over our alternative interconnect.

The work is scheduled for between 29/8/2017 22:00 and 30/8/2017 06:00.

Most circuits will automatically re-conect but a few may require a re-boot or 30-minute power down. If there are any issues please contact support via the normal routes

post.merula.net – Slow [23/06/2017]

We are aware that our post.merula.net server was slow / unresponsive between approx 5pm and 8:30pm this evening.

This was due to a customer sending a significant volume of SPAM through the server. We have blocked the affected customer and cleared the Mail Queue on this mail server. Service is now restored.

NOTE that there is a small chance of some outgoing emails being lost while the queue was being cleared – although we believe all legitimate emails have been sent OK.

IF you have sent an email during this time via post.merula.net and have not received a reply you may which to re-send it to ensure it has arrived

We apologies for any issues caused here

UPDATE: leased lines outage earlier today

RFO 09:40am:

To fix an issue with transient IPv6 and other intermittent routing issues we had seen recently, we were obliged to upgrade the software on one of our core routers. This holds live and backup routes that allow a smooth failover in the case of a single router failing in London. However it now (in an undocumented change from the software supplier) appears with the latest software that the routers set themselves as live on both primary and backup routers – resulting in a routing loop for some IP addresses which had static IP routes originating from this one affected router thus not correctly falling over as previously was the case.

Again, please accept our apologies for this short outage. It shouldn’t have happened.

We are aware of the cause, the problem has now been fixed on this, the one affected router and we have also made sure that all others in the network have been checked and we are confident all are now running properly.

UPDATE 09:27am:

We are aware of the root cause — located at a core switch in our London locations — and are working on bringing this back into service. No ETA yet but we expect this to be resolved shortly. Apologies for the downtime some of you are experiencing.

09:09am We are aware of reports of leased lines down and are investigating. More updates here as we know the cause & ETA to fix.

INFO: supplier equipment upgrades overnight 15/16th June
