Official information request regarding network outages and connectivity
issues
I refer to your request for information under the Official Information Act 1982 (the Act)
dated 16th April 2024:
1. “In each of the past five years, how many tickets, issues or complaints have been
logged with the Digital Solutions (or its predecessor, ITS) service desk relating to
network connectivity issues?
2. In each of the past five years, how many major network outages have there
been? Kindly provide summary statistics for the length of those outages for each
year (i.e. longest, shortest, and median lengths).
3. Across the last five years, what have been the predominant (>10 per cent) causes
of major network outages? For example, x per cent may have been caused by a
power failure, y per cent may have been caused by a firewall failure, and z per
cent may have been caused by an authentication systems failure.”

Our reporting tool does not easily capture duration of outages but the Chief Information
Officer can confirm that the majority of network events are restored within 1 hour. There
have been 2 major exceptions to this. A power cable was severed to the university and
needed to be repaired by the electricity company. A change was made to the university’s
firewall, that needed to be rolled back. Both of these incidents took several hours to
remediate.
Predominant (>10 per cent) causes of major network outages in the last five
years
Predominant causes of major network outages (“Severity 1”) that meet the threshold for
“>10 per cent” are as follows:
• Device Fault – Network. Includes software (e.g. buffer overrun) and hardware
faults (e.g. fan failure): 35.5%
• Device Fault – Firewall. Includes software (e.g. buffer overrun) and hardware
faults (e.g. fan failure): 13.3%
• Firewall Change: 13.3%
