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.
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.
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.
