I’m not having the problems this time, but you are. Or so I’m told. If you can see this, then you’re not having problems, I suppose, but they are said to look like:

Your access to this site has been limited

Your access to this service has been temporarily limited. Please try again in a few minutes. (HTTP response code 503)

Reason: Exceeded the maximum global requests per minute for crawlers or humans.

Important note for site admins: If you are the administrator of this website note that your access has been limited because you broke one of the Wordfence blocking rules. The reason your access was limited is: “Exceeded the maximum global requests per minute for crawlers or humans.”.

As an aside, I’ll note that I have a “private” (i.e., I post whatever I feel like on it) blog at wmconnolley.blogspot.com. If every this site doesn’t work, try looking over there.

[Update 2017/07/17:22:00: thank you for your concern (or at least, those of you who were concerned. For the reset, well screw you too :-). I’m told the problems are now over, woot.]
