MAINTENANCE Completed City Fibre
AFFECTING
City Fibre

Dec 09, 12:01 AM (3¼ days ago)
CLOSED

MAINTENANCE Completed Email
AFFECTING
Email
STARTED
Dec 03, 09:00 AM (8¾ days ago)
CLOSED
Dec 03, 02:26 PM (8½ days ago)
DESCRIPTION
We will be doing some non-service affecting work on our email (POP3 and IMAP) servers. The work involves reconfiguring how our backend mail stores synchronise mailboxes between each other. We do not anticipate this to be service affecting hence doing this work during the day.
Resolution: Monitoring shows no problems and a vast improvement in the speed of syncing mail between our servers.

MAINTENANCE Assumed Completed Amazon
AFFECTING
Amazon
STARTED
Dec 02, 09:30 AM (9¾ days ago)
DESCRIPTION
We are in a position where we are now able to re-enable one of our interconnects to Amazon/AWS. This will move most Amazon traffic away from our peering with them over LINX to the direct interconnect we have. This is planned for Tuesday morning at around 10AM. (This was scheduled for Friday 28th, but as it was Black Friday, we've moved to Tuesday)

MAINTENANCE Assumed Completed Data SIMs
AFFECTING
Data SIMs
STARTED
Nov 29, 09:00 AM (12¾ days ago)
DESCRIPTION

Our old Data SIM service is due to be switched off by the network provider this weekend. Affected customers have already been posted new 'Bluewave' SIMs, and many customers have already swapped over. This post is here in case customers are unaware of this happening.

There is information on our News page regarding the need for the SIM swap. If customers are having problems then please do email us over the weekend or get in touch with us on Saturday (10am-2pm) or during the week.

UPDATE: SIMs did not drop at the weekend as expected. This means customers have a bit more time to migrate to the new SIMs. We're not sure when the old SIM service will stop working though.


MINOR Closed Routing to BT
AFFECTED
Routing to BT
STARTED
Nov 28, 10:30 AM (13¾ days ago)
CLOSED
Nov 28, 10:45 AM (13¾ days ago)
DESCRIPTION
We're seeing odd routing problems and packetloss between us and BTs network - eg to IP addresses that BT host for their servers or broadband services, not our links to BT for our broadband services. We are investigating.
Resolution: This seems like the problem was at BTs end, we've heard from other ISPs who had similar routing issues to/from BT's network.

MAINTENANCE Completed L2TP
AFFECTING
L2TP
STARTED
Nov 24, 03:15 AM (18 days ago)
CLOSED
Nov 24, 03:30 AM (18 days ago)
DESCRIPTION
On Monday 24th November, at 3:15AM we will be upgrading the software on one of our L2TP servers (l2tp.aa.net.uk) This will cause some L2TP customers to drop and reconnect twice as this happens. (Twice, as whilst the router is upgraded connections will reconnect to the other L2TP server, and then will moved back once the upgrade has completed.)
Resolution: The upgrade completed successfully.

MAINTENANCE Completed BT
AFFECTING
BT
STARTED
Nov 19, 09:00 PM (22¼ days ago)
CLOSED
Nov 20, 07:05 AM (22 days ago)
DESCRIPTION
BT have planned work on one of the fibre pairs on one of our hostlinks. We will take this link out of service to avoid disruption to customers.
Resolution: The disruption between 02:29 and 02:37 was caused by BT's Planned work. However, a communications error on our side meant we shut down the wrong link to BT. We do apologise for this! We do not expect any further drops though.

MINOR Closed BT
AFFECTED
BT
STARTED
Nov 18, 11:00 PM (23¼ days ago)
CLOSED
Nov 18, 11:50 PM (23¼ days ago)
DESCRIPTION
There were several 'blips' overnight that affected some BT customers between 11PM and midnight. Service has been stable since, we are investigating the cause
Resolution: This was caused by BT planned work, which went wrong. They are planning work on the other pair of fibres on this hostink during the early hours of Thursday 20th November, but we will take this out of service beforehand.

MINOR Open ZyXEL
AFFECTING
ZyXEL
STARTED
Nov 18, 04:40 PM (23½ days ago)
DESCRIPTION

ZyXEL have published a security advisory which covers some of the ZyXEL routers we have provided our customers, the DX3301 and VMG3927.

New firmware has been released. Customers can either load this manually, or use the 'Upgrade Firmware' button found on the router information page on our Control Pages.

We have received further clarification that the vulnerabilities affect the router's web interface when exposed to the internet. Routers we configure for customers will have the web interface only allowable from our office IP range, and so this vulnerability is deemed low risk. We still recommend that customers upgrade. The upgrade process will take a few minutes but it does not reset the configuration.

We will make direct contact with customers with these routers, and support staff will mention this if and when they are talking to customers and notice the firmware is out of date.


MINOR Closed BT
AFFECTED
BT
STARTED
Nov 16, 10:20 AM (25¾ days ago)
CLOSED
Nov 16, 03:45 PM (25½ days ago)
DESCRIPTION
At 10:20 a number of BT lines dropped, we're investigating.
Resolution: At 10:20 about 30% of customers dropped there connection and reconnected within a few minutes. Service was back to normal by 10:28. One of our 4 links to BT had loss of light. BT replaced a faulty LIM (Line Interface Module) card at Greenwich later in the afternoon.

MINOR Closed AWS
AFFECTED
AWS
STARTED
Oct 23, 09:45 AM (1½ months ago)
CLOSED
Nov 20, 10:13 AM (21¾ days ago)
DESCRIPTION
We've had reports of customers having problems routing to some IPs within Amazon
Resolution: Separate to the routing problem, both of our Amazon interconnects are being migrated to different equipment at Amazon's end. They are out of action for the moment. We still have peering to Amazon over LINX.

MAINTENANCE Completed DNS
AFFECTING
DNS
STARTED
Feb 11, 03:30 PM (10 months ago)
CLOSED
Nov 24, 09:29 AM (17¾ days ago)
DESCRIPTION

This notification is for customers who run their own authoritative DNS servers and use our secondary-dns.co.uk as secondary (slave).

As part of our DNS infrastructure project we will start to initiate Zone Transfers from an additional set of IP addresses.

You will still send your NOTIFY to secondary-dns.co.uk but you will start to see AXFR requests from an additional set of IP addresses.

Therefore, please update your ACLs to allow the following addresses in addition to what you have at the moment:

  • 194.4.172.3
  • 194.4.172.4
  • 194.4.173.3
  • 194.4.173.4
  • 2001:8b6:1:0:194:4:172:3
  • 2001:8b6:1:0:194:4:172:4
  • 2001:8b6:2:0:194:4:173:3
  • 2001:8b6:2:0:194:4:173:4

Please update your ACLs by March 11th.

We will have an overlap of using the existing DNS servers and the new DNS servers. As part of our testing we will start to use the new IP addresses from February 17th


Resolution: This is now live.
