Loss of Resilience – Huntingdon – Resolved 27/06/2020

One of the two 10G Links into our Huntingdon Data Centre – running from Huntingdon to Manchester is currently down. This is primarily a backup link.

However this does mean that both Huntingdon and Manchester have reduced resilience currently and are ‘at-risk’

The fault has been raised to the carrier and they have already commenced work to restore service

We will update this post as we know more

[Update 23:30]

Update from our suppliers:

Our engineers have arrived on site and performing site checks. We have scheduled for splicers to be dispatched and are awaiting their ETA.

Next Update Due: 01:00 26/06

 

[Update 0:30]

Update from our suppliers

Our engineers have found a fibre event 6km from the Leicester exchange. Engineers are making they way to the area where there is a confirmed fibre break.

[Update 2:30]

Our field teams have located damage on Aylestone road at the junction of Putney Rd West. Road works have cut and dug up multiple cables causing significant damage to cables and joints. It will take longer than expected to assess the full damage before a fix plan can be drawn out.

[Update 5:20]
Damage Confirmed:
1 x 160f
4 x 24f
4 x 144f
2 x 8f
1 x 96f
2 out of 4 sub ducts damaged

Cause:
Road works. Cables chewed up by a rotary cutting machine. Severe damage has been caused to cables.

Update:
construction have completed installation of x 2 new ducts
Cable gang are onsite.
replacement cable has been ordered.

Plan:
Pull in replacement cables when it arrives into the adjacent joints and resplice to restore.

[Update 6:30]

Replacement Cable will start arrviing between 6:45 – 7:00

Once it has arrived the cable gang can start the process of pulling it in.

[Update 9:00]

Our suppliers are continuing to replace the damaged fibres into the new ducts. Once this is completed they will splice the new fibre

[Update 16:00]

The Civil work needed to install this fibre is complete and the replacement fibre is in the ground. Work to splice the new fibre is ongoing. Given there are over 600 fibre pairs affected this will take several hours to complete.

We will continue to update as we have significant information

[Update 11:00 27/6]

All replacement fibres are in place and splicing has completed

However we are still seeing business impact and have sent ground teams to investigate a Transmode link that has remained down.
Once the investigating engineers return with more information we will be in touch to advise of our next actions.

[Update 12:00 27/6]

We currently have Field engineer red light testing the span of the Transmode link.
Once we have further information we will update you again.

[Update 17:00 27/6]

The Link has been up since 13:00 today – there has been some disturbance however this has been stable since 16:30 today. The suppliers have stated that all work has now been completed on this complex fault. We will monitor the link but we believe this is now stable and we have full resilience to our Huntingdon & Manchester loocations

As part of the certificate renewal on our webmail server – the URL for webmail has changed from https://mx1.merula.co.uk to https://mymail.merula.net

The physical server email accounts etc remain the same – it is just the URL for webmail that has changed. If you prefer to access your email from an email client – you can also change the SMTP/IMAP/POP3 servers to the same name – mymail.merula.net

If you do not have a merula.co.uk email account you are not affected by this change

As ever if you have any questions please contact support via the normal routes

 

Phishing Email / Text

We have seen a number of email and text messages in a format similar to the below

These messages are not genuine and you should not click on the link – or send any details if you receive these

We have (we believe) blocked this site being reached from the Merula Network – but you may still be able to reach these if you are connected via your phone etc.

We would strongly advise customers to be wary of clicking on any link they are not 100% certain is genuine

 

 

Caching Name Server issue [resolved]

We are sorry for any issues here

[update] Thos issue should now be resolved. If you are seeing any issues please call or email support as normal

OUTAGE: scheduled maintenance DSL overnight 10th April 2019

As part of our commitment to service improvement, we would like to inform you that we will be performing planned critical maintenance as part of capacity upgrades on our core network

Maintenance window start: Wednesday 10th April 2019 23:00 GMT

Maintenance window end: Thursday 11th April 2019 06:00 GMT

Expected impact duration: The work will impact some of our DSL subscriber customers, and they will see an intermittent service within the maintenance, with a short period of down time. Service should be restored automatically but it may require a router re-boot. If after this action, service hasn’t been restored, please raise a support case in the normal manner.

OUTAGE: scheduled maintenance broadband 16th/17th Feb 2019

We will be upgrading some of our core routers that terminate broadband sessions during the course of the weekend – each will be down for less than 30 seconds for an important firmware upgrade. These will be staggered over the two days. Most affected customers will reconnect within seconds automatically. If you have any issues, please reboot your router and if that fails for any reason, please call into or email support in the normal way. This will only affect ADSL, FTTC & FTTP lines.  

CLOSED: Portal diagnostics

UPDATE: the supplier code issues have been worked around and all tests are now available again.

—————————–

We are aware of issues working with the APIs from the suppliers that’s affecting the ability to run diagnostics via the Merula portal (https://adslreports.merula.net); we are working on this now and will advise here as soon as this is resolved. Apologies for this loss of service.

OUTAGE: overnight works

RESOLVED: the fibre break was fixed at 8:53pm last night and all services are back to normal. This ticket is now closed.

UPDATE 15:50 — our supplier advises “in relation to the issue identified in Cambridge area regarding loss of service. We are still working hard to resolve these issues as a priority.

Due to heavy traffic in the area, this is impacting our ability to get into the pit location necessary to move services onto spare fibres. Traffic management is required to safely carry out the work and this cannot be implemented until 20:00 this evening due to local authority restrictions.

From 20:00 onwards we can commence repairs so we should see services begin to come back online overnight this evening.

Please accept our apologies at this time as we are treating this matter with the utmost urgency.”

UPDATE: 14:45pm — because of the amount of splicing work needed and the traffic management problems at this location, the ERT has been pushed out to 20.45 today.

UPDATE: 13:00pm — Traffic management is only permitted until 1530Hrs but traffic lights and barriers are on site ready to go. We’ve not been advised of a new ERT as yet.

UPDATE 12:30pm — work continues on-site at the node. Raised for traffic management. Has ERT for 15 minutes time but engineer still working and waiting for response from traffic management team.

Next update due at 1300Hrs.

UPDATE 10:31am — at 1008Hrs an engineer arrived on site. The overnight change was moving to new cable but there appears to be a fibre break. No ERT at present.

UPDATE 10:11am — this is now being treated as a high priority fault as completion has overrun and classified as a MSO due to the affect on Merula (and other) customers through this node.

UPDATE: we are escalating this for a substantive update as the works have again over-run their new completion time.

Emergency unscheduled works by one of our main backhaul suppliers have overrun and mean that one of our 1Gb links to London from the data centre here in Huntingdon is hard down. Traffic is being routed via one of our backhaul links but as this is slower you may see some slowness on some traffic until this work is completed.

We have been told that the work was due to finish at 6am but this has now been pushed out to 8am.  We will continue to update here. Our apologies if this affects your connection(s).

Emergency work 15/02/2018

Our supplier has identified a potential issue with a fibre bearer which holds some backup links to our Huntingdon Data Centre. They are making a config change to correct this overnight.

As these are backup links it should not have a significant impact but there is some chance of packet loss as the link drops / returns as the network re-converges.

We will update this post as the work progresses
