Identified - We are still in communication with Sectigo regarding the rate limits that were reached. The rate limits were reported to have been lowered globally in order to reduce the impact and performance to Sectigo's customer base. SSL issuance may be intermittent during the time in which the limitations are reached.

Update - We are still in communication with Sectigo. They have reported that the issue has been escalated as urgent to their development team in order to investigate as soon as possible.

There is a chance that the API call limit we hit resets at some interval and the problem will resolve itself on its own, however, we will continue to monitor and provide updates as necessary.

Investigating - We have been notified regarding Partners being unable to purchase SSL certificates. It appears that we may have hit an API limit. This will also prevent free SSL certificates from being processed at this time.
