DESCRIPTION
It hasn't been very long since our last round of software upgrades, but we have new software we're wanting to apply. We'll be performing overnight software upgrades on our pool of LNSs and BGP routers, starting Sunmday 13th July. 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 this week 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 (5¼ 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
STARTED
Feb 11, 03:30 PM (5 months 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


MAINTENANCE Assumed Completed authoritative DNS
AFFECTING
authoritative DNS
STARTED
Jun 03, 10:35 AM (1 year 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
