* Only users that submitted at least one job were counted.

Number of support requests*,**

Support channel	Number of support requests
OTRS ticket system	3,682

*Tickets from the SIS top-level and from the SIS::Leonhard Med queue are not included, even if they were handled by the HPC group
**After the cyber attack of 15 May 2020, we temporarily stopped using the ticket system and got around 1000 email requests between 15 May 2020 and 22 June 2020 (39 days) that were not moved to the ticket system
