Organisations are intended to receive a minimum availability of 99.7% over 12 months, across the network. This was true for 90.3% of all sites at the end of January 2009.

All organisations should receive a time to restoration of service of less than ten hours following an outage. Over the 12 months ending in January 2009 on average 88.92% of outages were resolved within 10 hours (87.30% at the end of the equivalent 12 months last academic year). There were 48% more incidents this quarter than there were in the same period last year.

There was one widespread outage in December 2008. Twenty sites connected to JANET via the London Metropolitan Network (LMN) suffered a 27 minute outage due to a router problem. There were no widespread outages in November 2008 and January 2009.

There were 107 maintenance periods affecting connections during this quarter (214 last quarter and 323 in 2007/08 Q2). These were comprised of 98 scheduled maintenance periods (notification given at least two weeks in advance) and nine emergency maintenance periods. All nine emergency maintenance periods were carried out during working hours.
