8pm Pacific: We are investigating a slowdown in our admin. We will update as we have more information.
11pm Pacific: We are continuing to monitor and diagnose, but service has been restored.
RESOLUTION UPDATE: Thursday, April 2, 2020, 10am Pacific:
We have determined the root cause of this performance issue, and have resolved it. In certain store-related actions (modifying the store via the admin or API), as part of clearing the cache, we triggered a cache invalidation request to our backup CDN. Changes in that system resulted in rate limiting to their API, and since this particular request was blocking, it resulted in a slowdown to certain write behaviours in the admin and API.
We have resolved this issue at this point. We apologize for any inconvenience you may have experienced withslow admin page loads.
