My static home IP was blocked by my new energy supplier.
It took almost 4 months to get through to someone who would accept my problem wasn't forgetting my password.
In the end, I was pointed to their third provider and told "sort it out yourself, not our problem". Thankfully that other company had a reasonable-ish appeals process...
...obviously I got relisted in their db a few times but things seem to have calmed down now.
Ah, "Reputation" and "Threat Intelligence". One of the things I didn't expect but should have after BeyondCorp and Zero Trust is that some people would decide they need to go the exact opposite direction.
Instead of designing our systems as though they all face the hostile public Internet like Google, why not instead police all of the public Internet as though it's our internal network? That way we don't need to adopt any actual security practices. What could go wrong?
As you saw, basically everything, all the time.
I actually moved energy supplier a few months ago. I had a good quote from a new supplier, and when I tried to sign in to see how close the quote from my old supplier was their site wouldn't load in my browser, tried again a day later, no joy. OK cool, bye then.
One of my coworkers ended up blocked because Amazon maintains a block list of bot like users and our WAF was subscribed to it. This coworker was using scrapers for find GTX 3080s.
Surprisingly, Amazon does not block customers they put on this list.
