MAINTENANCE Planned Network
AFFECTING
Network
STARTING
Oct 09, 01:00 AM (8 seconds ) Starting soon
DESCRIPTION

We'll be performing routine overnight software upgrades on our pool of LNSs and BGP routers, starting Thursday 9th October. One LNS will be done per night, and this involves moving lines between the LNSs and upgrading when lines have been moved off. Customers may see a PPP drop and reconnect in the early hours of the morning as this work is carried out.

Upgrades to our BGP routers will also happen overnight but should have little to no impact.


MINOR Open Email
AFFECTING
Email
STARTED
Feb 03, 09:00 AM (8 months ago)
DESCRIPTION

Over the past week we have seen a huge number of 'bots' trying to guess customer email credentials in order to try to send email through our outbound email servers: smtp.aa.net.uk.

The attempts were being blocked due to wrong passwords being used, but this caused significant load on our severs due to all the database lookups involved. To address this, we are blocking IP addresses that are listed on the Spamhaus 'Exploits Blocklist (XBL)' and the Spamhaus 'Combined Spam Sources (CSS)' lists. -These are typically IP address known to have hijacked in some way or known spam senders.

This has reduced the load on the email servers significantly, however we are are still blocking around 1.5 million unique IP addresses each day.

We have had a small number of legitimate customers affected by this as their IP address is on these blocklists. (IPs can be looked up on https://check.spamhaus.org). In these cases, please do contact support and we can discuss workarounds.


MAINTENANCE Assumed Completed DNS
AFFECTING
DNS

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


MAINTENANCE Assumed Completed authoritative DNS
AFFECTING
authoritative DNS
STARTED
Jun 03, 10:35 AM (1¼ years 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


MINOR Closed BT

CLOSED
Oct 03, 05:35 AM (5¾ days ago)
DESCRIPTION

Between 5AM and 5:30AM we saw a reasonable number of BT SoGEA lines drop for around 100 seconds and reconnect.

They only dropped off once, but over a period of around 30 minutes we saw a few hundred drop and reconnect. As far as we can see the only common factor is that they are BT SoGEA lines. We don't have any planned work notifications for work on this scale, and the sites are dotted around the country.


Resolution: These lines were migrated from VDSL to SoGEA two days ago and we suspect this could be a normal, automatic, DLM resync event.

DESCRIPTION
Between 20:21 and 20:28 some VoIP registration and call attempts were failing. This happened during an upgrade of one of our database servers which had an unexpected knock-on effect. We're still investigating this in more detail, and we apologise to those affected.
Resolution: The cause has been identified and a code change has been implemented.

DESCRIPTION
One of our upstream carriers (Magrathea) are migrating parts of their network to new infrastructure. We expect very little disruption to service and backup carriers are always in place. Update from carrier. "Whilst this work has been planned to avoid any major downtime, very brief interruptions of service may occur on parts of the network as connections are migrated to the new infrastructure."
