Planned Work

INFO: mail-server upgrade 4th April 2017

One of our clustered mail-server machines will be updated and moved to a new location at some point tonight. This will not involve any down-time but mail delivery may be slightly slower than usual for a period of up to 2 hours as the databases sync back.

INFO: fibre ring maintenance 7th April

 

This work will upgrade the capacity on one leg of our dark-fibre ring. Whilst it won’t cause any outages, we are at elevated risk during the maintenance window and there may be brief transient routing issues when the fibre is brought back on-stream.

Maintenance Window: 21:00 – 07:00 GMT

Primary Date: 07-Apr 2017

2nd Primary Date: 08-Apr 2017

3rd Primary Date: 09-Apr 2017

Location of Maintenance: London

Reason for Maintenance: supplier will perform fiber maintenance to add capacity

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.

INFO: supplier equipment upgrades 23/24 Feb

We don’t expect this to materially affect any of our services but there may be a few instances of slight packet loss or routing transit issues during this window.

Start: 2017-02-23 00:00:00 GMT (UTC + 0)

LAN(s) AFFECTED
London Juniper

INTRODUCTION
This maintenance is scheduled for the 2nd stage of Juniper software and Routing Engine upgrades.
During this maintenance we will replace both 32 bit RE-S-2000 Routing Engines in Edge1,
Edge2 and Edge3 THN (Telehouse North) with 64 bit RE-S-1800×4 Routing Engines. We will also upgrade the Junos version to 15.1F6-S3 from 13.3R5-S4.1.
All members connected to edge1-thn, edge2-thn and edge3-thn shall experience downtime of up to 20 minutes whilst the RE’s are swapped and rebooted.

Manchester Network Upgrade 14/08 – 15/08

During the afternoon / evening of the 14th August we will be performing a range of upgrades at our Manchester PoP. These include

  • Replacement of UPS  Batteries
  • Upgrade Core Switches
  • New Access Switches
  • Upgraded Core Routers
  • New Servers

During some periods of the maintenance routes that would normally route via Manchester will take an alternative route. It also means that some backup leased Lines will be unavailable for a short period.

While the maintenance window is wide we hope that the actual core network will not be affected for more than an hour or so – hopefully less. All the replacement hardware has been setup and tested in our Lab. Note that we are not anticipating any issues with our core network in any other location and Broadband, etc should be affected – However it should be considered ‘at risk’. These upgrades should further enhance the stability of our core network

If there are any questions please raise them via the support mailbox

Telehouse Maintenance Tonight (06/07/2016) [ COMPLETED]

Following on from the outage last week we are seeing a issue with some IPv6 traffic being sent via our thn-gw1 router. To fix this we need to restart one of the routing processes. While this is low risk we will perform this out of hours tonight at approx 10pm.

We are not expecting any issues from this – however there is a small risk of a network blip if we have to reboot the router rather than restart the stuck process.

We will update this ticket as the work progresses

This work is now completed and the issue should be resolved – if anyone has any issues please contact support in the normal way

 

Notification of Planned Work: 12th August Telehouse North – Virgin Media Business

We need to let you know about some maintenance work that will be taking place on our network. We will be upgrading one of our network back-haul links into the VMB node at our London, Telehouse North site.

Planned Work Start (Local UK): 12/08/2016 00:01 Planned Work End (Local UK): 12/08/2016 06:01

Impact: There will be a loss of service at some point during the timeframe stated above whilst we complete the maintenance work. You will see several interruptions to your service during the 2 hour outage window. We have planned and believe that all circuits will automatically return to service after the work is completed

Only those circuits supplied via VMB will be affected. Please email into support in the normal manner if you have any questions.

UPDATE: upgrading Virgin Media fibre into 5 Avro Court 23rd & 24th March

In preparation for additional fibre capacity being brought into the building tomorrow evening — with work commencing on both dates at 6pm — tonight we will force the traffic over our other two backup supplier back-haul channels to ensure that when the Virgin circuit is swapped over to the new fibre connections tomorrow, no down-time is seen.

This may result in some very temporary route instability and slight increase in routing times seen as the work starts & ends tonight and tomorrow. This should resolve automatically.

As always, if you have any concerns, please contact support in the usual manner.
