Service hours

 

Normal operating schedule

All services normally run with operations staff present (attended operation), subject to the holidays and vulnerable periods shown below, as follows:

Monday to Friday 08:00–17:00

At other times they run with no operations staff present (see unattended operation).

Holidays

UIS is closed on bank holidays. In addition, UIS will close at 17:00 on Tuesday 24 December 2019 for the Christmas/New Year holiday and re-open at 08:30 on Thursday 2 January 2020.
 

Unattended operation

When a service is running unattended, if it should fail, the service might not be reinstated until the next period of attended operation. In practice, staff monitor services from time to time outside normal working hours and are often able to reinstate them, but this can not be relied upon.

 

Vulnerable periods

The following periods are designated as vulnerable. During these periods, services may be interrupted for maintenance or other dedicated work.

Desktop Services*, DS-Print Scheduled Downtime, Hermes* , Jackdaw*, Falcon*, Managed Web Service*, Lookup* Monday to Friday 07:30–09:00 [1] 17:00–19:00 [1]

*Announcements about when these services are likely to be disrupted during vulnerable periods are made 24 hours in advance (or, for deferred emergency maintenance, by 15:00 the preceding period) via the IT Service Status system and, where possible, on the appropriate systems.

 

Notes:
08:45–09.00 and 17:00–17:15 are avoided when possible.
17:00–19:00 is not normally used for non-urgent work that might disrupt a significant part of the UDN.

We're planning the following maintenance changes to the University's IT systems. Where possible, work is kept within the vulnerable periods advertised above.
