We have scheduled to perform a system software upgrade of the CAcert webserver on Wednesday December 29 2010, starting at 10:00 CET. The upgrade will last at most until 13:00 CET, but we are aiming to complete well before that time. During the upgrade, the CAcert webserver will be unavailable for all users, and no certificates can be signed or revoked. All other CAcert servers will remain up and running though (including OCSP and CRL services).
