Looking at my firewall at the time (a Watchguard XTM 22), it was getting significantly more traffic and attack attempts around the clock than on Plusnet, to the point where the device was struggling to keep up with it.
I brought this up with CS and they tiptoed around it and gave me a free Zyxel modem to replace my old BT Openreach-supplied one. That has somewhat helped as the line was more stable but I've had to go as far as to replace my firewall/router (something I was planning to do, so not the end of the world). I now have a fairly beefy box running OPNsense.
Its also became more apparent over time that AAISP are the target of DDoS attacks. Now, I appreciate they're part of the course for any ISP, but I'm concerned that either AAISP are the target of more than you're average ISP based on customer size, or they're just not that great at mitigating them. It looks like much of their network relies on their own Firebrick boxes, which could be a double-edge sword of being their own networking experts, or not having the resources to match other hardware manufacturers.
It seems to be a common occurrence now to be knocked offline for decent periods of time. When checking on my phone, most of the time the AAISP website is down, suggesting the whole network has been bumped offline. Most of the time I don't see anything on their status to acknowledge it, the most recent one being an exception.
