Emergency Planned Work Affecting some DSL Connections 16/05/2017

One of our carriers (TalkTalk) is performing some emergency planned works on their interconnect in Telehouse North. We have resilient Interconnects in other locations however during the work you may see your connections drop and re-connect over our alternative Interconnect

The work is scheduled for between 16/05/2017 20:00 and 17/05/2017 06:00

If there are any issues please contact support via the normal routes

Name Server Upgrade [01/05/2017]

We are upgrading the hardware and software for one of our name servers in Harbour Exchange Square London during the afternoon / evening of May 1st. While this will not directly affect customers – they may find some name resolution is show while the old server is removed and the new hardware installed. The new server pre-configured and should work identically once installed. However as with all upgrades there is a risk

We will upgrade this post once the upgrade is complete or if any issues occur

This work was completed. Further work will be completed on our second name server in Telehouse North in the coming days

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: 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)
End: 2017-02-23 04:00:00 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
