OWT performs maintenance every THURSDAY morning between midnight and 2:00 AM. During that time almost every service is affected briefly. If a server or other equipment requires service we always try to do it during this maintenance window. This means that any service COULD be down for the entire window without prior notification. This is quite rare but should you notice service disruptions during this window we simply ask that you consider that this could be the reason.
Just to be clear... Thursday at 12:00 AM is the midnight at the end of Wednesday.
