I have been reading this forum regularly, usually several times per day, think I have even hit all different hours of the day over the last few weeks.
Several months ago, I definitely saw a ton of problems at the same time others were complaining about forum slowness or errors.
Recently (last several weeks), I have observed no issues whatsoever. So I don't believe the problem today is exactly the same as several months-ago.
I realize this is only 1 data-point, but I think my DNS filters ads, so I wonder if the current cluster of problems might have ad-serving as a key factor..?
