We have implemented multiple changes that have improved the duration of checknows and pre-publish checks, and we're now back to normal operations. Thank you for your patience.

We have implemented a fix to speed up the execution of single page checks (checknows) and pre-publish checks, and will be monitoring the impact for a while. So far we have registered a multi-second reduction in processing time, so we are optimistic, but we still want to see the effect on higher activity levels.

Updated incident to reflect that this is also affecting pre-publish checks.

We have identified a bottleneck in the system that was surfaced due to recently added load. We're working on eliminating this bottleneck, and hope to be back to normal performance levels soon.

Single Page Checks are currently processed slower than usual. We are investigating.
