What should I do if my CCUs spike or drop unexpectedly?

Since CCUs can serve as an indicator of an application’s health or performance, you should attempt to correlate unexpected spikes or drops in Cloud Capacity Units with development activities such as code changes, site configuration changes, and environment configuration changes, or with changes in traffic. While modest spikes in CCUs should be expected during mid-day traffic peaks or whenever cron runs, unexpected spikes that jump too high and occur too often could be indicative of a caching or configuration problem that could lead to a temporary resource limit being imposed on your environment by Acquia. In the unlikely event that this happens, create a Support ticket.
