So what happened was we were cruising just fine after the fixes I put in months ago, but then a couple of days ago a bot hit us (and Tractorbynet) pretty hard. Several automatic web-crawlers were using 100 connections up individually. And this happened about a dozen times. So while the server was able to 'recover' and try to keep serving web pages it was still hanging up on these 1200 requests that kept asking.
We put in some automatic blockers now. If anyone tries to take 20 simultaneous connections at once, they'll receive a temporary ban.
No users should be able to do that with their PCs or phones, it would take special tools. So no worries about accidentally being banned. However, if you notice any negative behavior about the site in the next week, please comment here or make a new thread or otherwise let us know. But fingers crossed we're good again.
