MAINTENANCE Assumed Completed authoritative DNS
AFFECTING
authoritative DNS
STARTED
Jun 03, 10:35 AM (1¾ months ago)
DESCRIPTION

This is only relevant to customers who run their own authoritative DNS servers and use our secondary-dns.co.uk as an additional nameserver.

Overview: We run a "secondary" DNS service for customers where they run the master DNS server and we are secondary slaves. We have a project underway that involves migrating all our authoritative DNS services to a new platform. As part of this we are needing to disable some of the automation we do for adding and updating the customer's master IP address automatically.

The change: From June 17th, If you run your own master DNS server for your domain(s) and secondary-dns.co.uk is a slave, if you change the IP address of your master you will need to contact support@aa.net.uk to request us to update our side.

We have more information about our Authoritative DNS project on our Support Site: https://support.aa.net.uk/New_Authoritive_DNS

MAINTENANCE Assumed Completed SMS
AFFECTING
SMS
STARTED
Apr 08, 02:13 PM (3½ months ago)
DESCRIPTION
This work has started, but we did not do a planned work as expected it to be seamless. Sadly that was not quite the case today, so this is more detail on what we are planning over the next few weeks. The main thing is, any problems, please tell us right away.
  • Some cosmetic improvements (nicer format phone numbers) in emailed or tooted SMS (done)
  • Additional options (such as forcing the email/toots to be E.123 + format numbers) (done)
  • Additional options for posting JSON to http/https (TODO)
  • Allowing SMS to be relayed (chargeable) to other numbers (done)
  • We already allow multiple targets for a number for SMS (done)
  • Some improvements for 8 bit SMS, which are rare, as we previously treated as latin1, which is not correct (TODO)
  • Some new features for trialling a new SIP2SIM platform (TODO)
  • Improve "visible" format for content in email/toot when special characters are used (e.g. NULL as ␀) (TODO)
The 8 bit data format changes are likely to be the least "backwards compatible" changes, but should not impact anyone as they are not generally encountered. I.e. incoming SMS will rarely (if ever) be 8 bit coded, and when they were, we would get special characters wrong. Similarly, sending 8 bit SMS would only show the expected characters on some older phones, and would be wrong on many others as the specification does not say the character set to use. We will, however, handle NULLs much better, which are relevant for some special use cases.

CLOSED
Jul 21, 03:40 PM (5½ days ago)
DESCRIPTION
We'll be doing a little bit of work on our NAT64 gateways. This will happen during the afternoon/evening of Sunday 21st July. Part of our work will involve testing our failover. There may be short periods of time when the gateway is unavailable. (This is only relevant to those customers who are IPv6 only and specifically make use of our DNS64 and NAT64 services.)
Resolution: This work has been completed.

MINOR Closed L2TP
AFFECTED
L2TP
STARTED
Jul 12, 04:33 PM (14¼ days ago)
CLOSED
Jul 12, 04:40 PM (14¼ days ago)
DESCRIPTION
We're investigating a large number of drops and reconnect on our L2TP service.
Resolution: This looks to be a repeat of the drop and reconnect incident we saw earlier in the week - A port flap on our Primary L2TP router caused our backup L2TP router to take over the routing of the service causing customers to drop and reconnect - then the primary L2TP router re-established itself and customers moved back once more. We'll investigate this in more detail to find the root cause of the initial port problems.

Jul 11, 11:50 AM (15½ days ago)
DESCRIPTION
At 11:21 we saw a small number of TalkTalk lines drop and reconnect. We're investigating.
Resolution: A TalkTalk backhaul connection failed (twice?) and traffic was re-routed, as a result a small number to TalkTalk connections dropped and reconnected.
