22/11/2018 – 09:00 – Outage Vodafone layer2 leased lines

Our network monitoring has alerted us to a small number of metro based layer 2 Vodafone circuits that have no service. This has also had an impact on broadband as well as services in to our Horsham based facility.

This was raised with the relevant teams last night and fibre engineers are already on site working on suspected damaged fibre to our selves and a number of other providers.

We have seen some services restore. Services with backup if affected will be operating on backup and wont be affected.

We will post further updates as they become available.

UPDATE01 – 11:02
Engineers have located the break and this will now progress to splicing.

UPDATE02 – 12:45
Engineers are continuing to work on splicing the damaged cable with spares.

UPDATE03 – 13:00
We are starting to see some services restore.

UPDATE04 – 14:25
As part of ongoing investigation into this issue, Vodafone are sending out additional engineering resources to their data centre.

Vodafone believe the break to be located 43 meters into the fibre handoff, which they are working on to resume full service.

UPDATE05 – 15:30
Engineers at the data centre are continuing to work with Vodafone fibre teams and resolve the second identified fibre break.

UPDATE05 – 16:45
Vodafone fibre engineers continue to examine the length of the fibre for further issues impacting service.

UPDATE06 – 17:55

Vodafone engineers remain on site tracing the underlying infrastructure so that a permanent fix can be put in place for all affected services. We continue to work with the carrier to expedite the resolution with regular communication.

Currently the agreed next stage is for engineers to work to determining the exact location for the fibre fault.

UPDATE07 – 18:45
All services have restored and we are awaiting a RFO. This will be provided on request.

26/09/2018 – 12:01- Broadband

We are aware of an issue affecting a large number of subscribers not being able to connect to the internet.

Initial reports and investigations seem to suggest this may be a problem within the wider BT Wholesale network as a number of other ISPs are reporting the same issues.

We’re continuing to investigate with our supplier and will provide further information when we have it.

UPDATE01 14:26

We can see that service was restored on the majority of circuits at approximately 1pm. We are still in correspondence with our suppliers in order to obtain information on the cause.

Planned Maintenance – 08/06/2018 – 00:01 till 06:00 (Leased Lines)

We have been advised by one of our fibre providers that they will be conducting maintenance on there hardware from the 8th June 2018 from 00:01 at Telehouse. This will affect a number of leased lines we provide via this location.

Please note this will affect clients with redundant fibre services whereby they terminate into the same core device on our network (carrier only redundant). Clients with DSL backup and or redundant fibre to our diverse cores at Telehouse (full redundancy) will not be affected.

Downtime is expected to be between 15 and 60 minutes all being well.

DNS Vulnerability affecting DrayTek

As per the various news reports there is a DNS Vulnerability affecting DrayTek routers. Over the past few days we have been auditing clients who have vulnerable models and a valid maintenance contract with ourselves. Work is already underway to patch devices in this instance however, we would advise all clients with Draytek hardware to check if there device is affected and update firmware as required:

Please see below 3rd party link for full details.

DNS Vulnerability Strikes Popular DrayTek Broadband ISP Routers

As a measure we will be blocking the DNS server used for the exploit on our network. However this could result is a loss of service should your device already be compromised. This unfortunately is a better option than using the compromised DNS server as detailed in the above news report.

If you have any questions please do not hesitate to contact us.

31/05/2018 – Broadband Supplier Maintenance 00:01 till 06:00

We have been advised our suppliers will be performing essential works on our interconnects which will cause a large number of circuts to lose their connection.

Work is anticipated to start at 02:00 and impact is expected to be 1 hour.

Our suppliers have advised this could be extended to 4 hours downtime.

Not all circuits will lose connectivity. However, if session disconnects during the work, they may not be able to reconnect until the work is complete.

We apologies for any inconvenience this may cause.

17/05/2018 – Ethernet Leased Lines – Migration – 20:00

As part of our planed network migration to Telehouse North and our own facility. We are now ready to migrate existing Ethernet fibre and EFM services from Goswell Road to Telehouse.

This work is planned to take place from 20:00 tomorrow night and is expected to take around 1 hour to complete with each service seeing around 5 minutes of downtime while VLANs are moved around the network to there new home.

Customers with backup ADSL or FTTC are unlikely to notice the drop as services will automatically re-route for the duration. Customers that have dual leased lines are also unlikely to notice a service drop as the move is being done in groups, so no 2 services are in the same migration window.

Updates to be posted on the night. Existing test services have been transferred so we do not expect any problems.

UPDATE01 – 19:45
Engineers are getting ready to start

UPDATE02 – 20:00
Work has started

UPDATE03 – 20:10
A problem has been found in our suppliers scripted code. They are attempting to fix this. Unfortunately this does mean additional downtime for the affected circuits.

UPDATE04 – 20:22
Code has been fixed however we are seeing MTU issues. They are being sorted for both this batch of migrations and the 2nd set.

UPDATE05 – 20:30
Stage 1 has been migrated and BGP sessions are back online. Stage 2 will now start.

UPDATE06 – 20:45
Stage 2 is complete, however there is a problem with 2 circuits.

UPDATE07 – 21:10
This work is now complete and all circuits are showing as online.

11/04/2018 – Email SMTP

We are aware of issues affecting SMTP email delivery on smtp02.structuredcommunications.co.uk

We always advise anyone using smtp02.structuredcommunications.co.uk to also setup smtp01.structuredcommunications.co.uk (this server is currently unaffected)

Due to the blocks in place on smtp02.structuredcommunications.co.uk it will take several days for the server reputation to recover.

04/04/2018 – Goswell Road (GWR) C3 Migration – 19:00

As part of our THN migration we are due to migrate services from C3 to C2 tonight. There will be no impact on major services such as broadband.

Works are only expected to take 10 minutes per service and affect a small number of bonded customers and hosted voice services.

UPDATE 01

This work is complete. However, during the works a configuration issue was made on a 10GB port that resulted in traffic being re-routed. This was spotted and resolved within minutes.

15/03/2018 – Telehouse North (THN) Enablement & Network Expansion

We are pleased to advise that we have recently added Telehouse North to our network location list and will begin enabling this for service over the next few months.

During this time we will be making changes to the current network located in Level3 Goswell Road in order to felicitate this. We hope to keep service disruption to a minimum and NOC notices will be published in advance of any works and the resulting impact they may have to your service.

Goswell Road as a result will be retired and all remaining services moved to our own in house data center. Details on this will follow as the THN migration is planned and the final build phase on our facility is completed.
