Resolved - Today, Cloudflare announced that their Web Application Firewall was blocking some legitimate search engine crawlers for some customers. This issue would only impact a legitimate crawler (such as Google) if it was attempting to crawl your site at this time. Otherwise, this issue will not impact your site.

Cloudflare is currently investigating a potential fix to correct this issue. To mitigate the impact on our customers, we are temporarily disabling rules related to this issue until Cloudflare has implemented their solution. Once the fix has been applied, the rules will be enabled again.
