I'd love to be able to blog in detail about denial of service attacks, what works, what does not, what we can or cannot do, but it would be mad to do so.
Suffice to say that anyone that wants to, and has a few bitcoins to spare (or fractions thereof) can engage one of the many botnets that exist and DoS the hell out of almost anyone, no matter how big.
It is unusual for an ISP to actually be the target, so much so that we did not cope well at all. We have all been working hard all day, and we all feel knackered. This attacker has caused the problems he wanted to cause, he has upset customers, and disrupted an ISP. Whack-a-mole does not really explain today adequately.
A customer had even ordered pizza for the staff, which is appreciated.
We still have much work to do even if the attack has now stopped, and we hope it has. Not only undoing loads of temporary hacks that cause their own issues, but planning for how to handle things better in future.
At the end of the day we are a small ISP and we try to do a good job for our customers. It is a shame when we cannot do that, and if anything we, or I, did upset anyone I am sincerely sorry for that. We also appreciate that it may have been something a customer has done to upset someone.
And, of course, I am sorry that our customers have suffered.
P.S. Increasingly looks like "not me" but a customer pissed someone off. I have had words!
