The system is particularly vulnerable when multiple cronjobs are running at the same time. We use cronjobs to have the system schedule certain tasks, and try to avoid too many of these happening at the same time. Whilst we prevent that from happening, today the situation was aggravated by the execution of Semrushbot: a bot which is automatically clicking on every possible link on the old schedule, causing a denial of service on our platform - leading to the system being unavailable across web and apps. We are currently blocking this bots range of IP addresses as a first containment measure, and returning to normal service levels.
