Due to exceptionally high temperatures in the Brno area, we will be implementing a precautionary performance throttling. The restriction will be implemented by setting the frequency of all CPU cores used to run virtual machines to their minimum supported value. On average, this represents a reduction to approximately 50 % of the maximum frequency. This will result in reduced computing performance and response times for all user instances.
