Failed to reach this forum this morning. Time was about 0800 UTC. Same thing as usually, Sucuri firewall error message. Seems to be a pretty common occurrence at around 0700-0800 UTC (mind you, it has been a while since I last tried accessing P-F at this time period, since it has so often resulted in the same result before).
Thought I'd report it in case folks think the issue has been fixed. Not a big deal for me, I did manage to find some actual work to occupy my time.
