On 5th March 2013 from 9:00 till approx 12:00 will be unavailable our trouble ticketing system (RT - rt3.cesnet.cz) due to necessary upgrade. During the outage will not be accessible neither the web nor the mail interface. E-mails sent during the outage (ie. for address meta@cesnet.cz) will be delivered after its end. We appologize for the half-day late response on requests.
