  1. monitoring Jul 30, 2023, 05:24 PM UTC

    This morning, CMS4Schools sites have been sporadically slow to load or unavailable. The problem was traced down to a malfunctioning server which was responsible for about 30% of requests. Some visitors would have had difficulty loading CMS4Schools sites during this time. The affected server instance has been removed from service and we're back to normal performance. We'll maintain a "Monitoring" status while the problem is addressed behind the scenes.

  2. resolved Jul 30, 2023, 05:45 PM UTC

    An issue with memory management has been found and corrected, and the affected instance replaced. We should be back to full performance and resilience.
