The Sketch Engine service at Masaryk University is currently down due to multiple severe hardware failures of the underlying disk array storage that occurred on November 23.

The hardware is currently being inspected by a vendor company and we cannot give any estimates on when the service might be back online. The data itself has been backed up on November 21. Any new data (e.g. corpus building) from November 21 (including) to November 23 might have gone lost.

In the meanwhile, users can use Sketch Engine via its main installation at by logging in via single-sign-on credentials of Masaryk University. Please note that corpus building is disabled to avoid synchronization issues.

In urgent cases where you either need corpus building or retrieve your corpora from backup, please contact Please note it may take several days to retrieve your data from backup.
