BT have a series of planned work that involves them replacing cable bundles that include our hostlinks - our interconnects into BT's network. We're not sure when these will take place, but will happen between 00:30 and 02:00 and will happen over three nights. This will cause 'blips' for many customers - lines will drop and reconnect within seconds or a couple of minutes.
We would usually be able mitigate any disruption by cleaning moving our traffic off the affected links. However, at the moment BT have not specified which link and the date that this work will happen. Thanks BT!
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.
