The 2007/08 Service Description (SD) prescribes service performance over a period of twelve consecutive months. This report covers the twelve months ending July 2008.
Traffic data were reported for between 97.5% and 98.5% of all organisations each month.
Traffic data for the following were not reported this quarter:
Month | Migration to PSBA (Wales)* | Other Incidents | Reasons for other incidents (where given) |
|---|---|---|---|
May | 5 | 1 | Traffic not monitored in May - site is currently undergoing B-end shift and running on temporary ADSL connection |

During 2007/08, 327 of 781 sites for which the Monitoring Unit received 12 full months of data were available continuously throughout the year.
Organisations are intended to receive a minimum availability of 99.7% over 12 months, across the network. This was true for 90.7% of all sites at the end of July 2008.
All organisations should receive a time to restoration of service of less than ten hours following an outage. Performance against this service level (SL) is calculated on a 12 month rolling average basis. Over the 12 months ending in July 2008 on average 87.51% of outages were restored within 10 hours (88.27% at the end of the equivalent 12 months last academic year). There were over twice as many outages in this quarter than compared to the same period last year.
There was one widespread outage in May 2008. All 57 SWERN sites lost connectivity for 11 minutes due to a configuration error.
There were two widespread outages in June 2008. The first was due to a SAP group storm causing poor performance and affected 12 sites on the ClydeNET regional network for 100 minutes. The second lasted 126 minutes and affected 10 sites on the KentishMAN regional network and was due to a SAP broadcast storm affecting routing equipment.
There were no widespread outages in July 2008.
Reporting indicates that there were no incidents that isolated any part of the core network during this quarter.
There were 336 maintenance periods affecting connections to client organisations during this quarter (176 last quarter and 231 in 2006/07 Q4). These were comprised of 324 scheduled maintenance periods (notification given at least two weeks in advance) and 12 emergency maintenance periods. There were eight emergency maintenance periods carried out during working hours.
JANET access to European NRENs is via a 10Gbit/s connection to GÉANT from Telecity R-PoP with a 2.5Gbit/s backup connection from Telehouse R-PoP. Peak traffic over the connection is normally around 2Gbit/s; however, it peaked at 5.03Gbit/s during this quarter.
An upgrade to the backup link to 10Gbit/s is underway. Both connections had 100% service availability over the past 12 consecutive months.
JANET access to the global Internet is via two global transit providers: TATA Communications (formally called VSNL) and TeliaSonera. Each company now provides four 10Gbit/s connection to two JANET PoPs at Telehouse and Telecity in London. Aggregated peak traffic reached 9.5Gbit/s early in the quarter, reducing to 6Gbit/s by July 2008. All eight connections were available throughout this quarter providing 100% availability over the past 12 consecutive months.
Peering with MCIX experienced an outage of 13 minutes in July due to a fault caused by a router memory issue. Peering with MaNAP Network had a break of 660 minutes in July due to a faulty card on transmission equipment which meant that the 12 month rolling average for this service was 99.87%.
All of JANET’s private peers were continuously available throughout this quarter.
A total of 421 fault reports were made during this quarter, five of which were not responded to within one hour, as required by the SD. At the end of the quarter the 12 month rolling average of faults responded to within an hour was 99.2%.
