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.

01171 01173 01179 01200 01214 01282 01372 01483 01485 01512 01513 01514 01515 01517 01518 01519 01527 01553 01604 01628 01905 01932 02010 02011 02030 02031 02032 02033 02034 02035 02070 02071 02072 02073 02074 02075 02076 02077 02078 02079 02080 02081 02082 02083 02084 02085 02086 02087 02088 02089 02311 02380

UPDATE 4 Network / Power Issue – Habour Exchange Square

We have lost power to our rack in Harbour Exchange Square. Our UPS held power for a while but the batteries are now exhausted meaning that services that are provided from Harbour Exchange Square are currently affected – this primarily relates to some of our Leased Lines which are single homed. Most other services have re-routed via alternative Data Centres.

The Data Centre Technicians are working to restore power  to the rack asap and we will then expect to see services recover here.

We will update this further as we have the updates.

Note this does not affect services (including leased lines) from other data centres – although there may have been some network instability initially

We are sorry for this issue

UPDATE 14:15 We are starting to see power restored to our rack though there are still some service affected – many are now restored. We are working through these issues and will update this further – However in many cases you should see service restored now

UPDATE 14:22 Equinix (Our Data Centre Supplier in HEX) have just emailed a Incident Update confirming a possible power issue at the facility. We are continuing to see services restore. There are a few remaining services down and we continue to work to resolve these asap. NOTE we have used the opportunity with the power loss to complete the UPS batter replacement – so that there will be no further maintenance on the power within our rack and in the unlikely event of another power fail we now have new batteries in the UPS

UPDATE 15:30 We have restored most services now although it seems the power failure has caused a switch to fail in the rack. All critical services have been moved off of the affected switch and a replacement is being organised to swap out hopefully later this afternoon/evening. There should now be no affected services – However the network should be deemed at risk due to the reduction in redundancy. We will update this once the switch replacement starts

UPDATE 21:10 A replacement switch is now in place and configured in Harbour Exchange square and the remaining services (and resilience) are now restored. There is a need to investigate the power issue further and the data centre may need to change the breaker we are connected to. However this will be a separate planned works and will be announced later. This may be at sort notice BUT will be out of core hours – and will not be today.

We believe service is now fully restored – IF anyone has any ongoing issues please raise them to support via the normal means.

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.

INFO: core router maintenance

We are seeing BGP issues affecting one of our core routers in HEX, London. This may involve the need to reboot this equipment late this evening. This will affect a few of our leased line customers only.

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
