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.

OUTAGE: leased lines down [resolved]

We apologise but are aware of a number of leased lines that have dropped because of a hardware fault on a core switch in London.

We will have this restarted within the hour and will be replacing this switch with a new one overnight. More status updates will be posted here.

[update] The initial issue was resolved before 6pm and the replacement hardware was installed in London this evening. This is being monitored but we hope this will resolve the issue once and for all

INFO: logging & reporting issues 4/4/17

We are seeing a few ADSL/FTTC lines that we are unable to monitor internally to track performance and transfer speeds. To overcome this we may need to reboot an internal switch that will mean that the PPP sessions on these few lines will momentarily drop. The circuits should all come back on-line automatically, but if you find an issue please re-boot your router to establish the session.

Outage thn-gw2 22/11/2016 [resolved]

Our monitoring started reporting that one of our core routers in Telehouse (thn-gw2) failed just after 19:15 this evening. We have now rebooted this and the router appears to be back and stable. We will investigate the cause of this and update the ticket as needed.

Most customers would not have noticed this (other than some slightly different routing) and possibly a few short periods of packet loss as routes re-converged. A small number of connections are directly connected and may have seen a longer outage as the router was restored.

We believe full service is now resumed – If you are seeing any ongoing issue please contact support in the normal way

We are sorry for any issues caused by this
