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.

INFO: Netgear router vulnerabilities

The following routers are vulnerable as below. New firmware has been released for some of the models and is available from here: http://kb.netgear.com/000036386/CVE-2016-582384

Vulnerability Note VU#582384

Netgear R7000, firmware version 1.0.7.2_1.1.93 and possibly earlier, R6400, firmware version 1.0.1.12_1.0.11 and possibly earlier, and R8000, firmware version 1.0.3.4_1.1.2 and possibly earlier, contain an arbitrary command injection vulnerability.

By convincing a user to visit a specially crafted web site, a remote, unauthenticated attacker may execute arbitrary commands with root privileges on affected routers. An unauthenticated, LAN-based attacker may do the same by issuing a direct request, e.g. by visiting:

http:///cgi-bin/;COMMAND

An exploit demonstrating these vulnerabilities has been publicly disclosed.

Netgear’s advisory confirms that the R6200, R6400, R6700, R7000, R7100LG, R7300, R7900, and R8000 are vulnerable, though affected firmware versions are not enumerated. The vendor has indicated that their advisory will be updated as firmware updates are released.

Possible LNS Issue 01/12/2016

We are seeing some oddness on one of our LNS routers which terminates some of our broadband circuits. We believe this is only affecting our management access and not the service provided over this.

We are working with the vendor to understand this and hopefully resolve this. Assuming this is not customer affecting we may need to reboot this LNS later this evening causing a brief network blip as the sessions re-connect.

IF we find this is affecting service earlier we may have to perform the reboot earlier. We will update this as we know more

 

Outage thn-gw2 22/11/2016 [resolved]

Our monitoring started reporting that one of our core routers in Telehouse (thn-gw2) failed just after 19:15 this evening. We have now rebooted this and the router appears to be back and stable. We will investigate the cause of this and update the ticket as needed.

Most customers would not have noticed this (other than some slightly different routing) and possibly a few short periods of packet loss as routes re-converged. A small number of connections are directly connected and may have seen a longer outage as the router was restored.

We believe full service is now resumed – If you are seeing any ongoing issue please contact support in the normal way

We are sorry for any issues caused by this

Update: PLANNED WORKS: transit backhaul maintenance work 22nd November

UPDATE: the supplier has advised that the work was incorrectly dated as tonight — it’s actually due to occur over the night of 22nd/23rd.

We’ve been notified of some urgent works occurring tonight on one of our backhaul supplier network interconnects.

This will only impact a very small number of our users who are routed through this. If after the work is due to complete, you’re still seeing issues, please reboot your router & if that fails to bring you back on-line, then contact support in the normal manner.

Maintenance window start: 22/11/2016 23:00

Maintenance window end: 23/11/2016 06:00

Telehouse Maintenance 9/10/2016

We are receiving alerts from our UPS in Telehouse. We have therefore scheduled a maintenance to visit the site and either replace the batteries on the UPS or replace the UPS as needed. Depending on the situation there may be an outage for Telehouse North based services late this evening for upto 90 minutes although we will of course keen this to an absolute minimum.

NOTE this UPS is in addition to the building UPS and Generator.

This work will affect most broadband services and some Leased lines.

We are sorry for the short notice but want to resolve the possibility of an issue as quickly as possible and at a time when least people are using the service

We will update this post as the work progresses
