The issue is rather simple, yet also complicated.
CloudFlare has been re-instated again, and it's going to have a couple of hiccups while things get ironed out. I'd rather we iron them out if at all possible rather than just dismiss it's use again, since fending off 200+ attempted spam account registrations PER DAY is getting mighty tedious and there is only so much that we can do within the SMF system to keep them out. If we can prevent them from even -hitting- the site in the first place, so much the better.
There will be randomized hiccups, but so far there are no black-listed domains or ips on CloudFlare for Hard-Light. When and where there are member problems, I will white-list the members access IP(s).
I know there are supposed to be announcements, but I personally wanted to see what level of impact that it would have without any forwarning, since reverting it off is a fairly straight forward process.
