Internet outage: Feedback

Friday, October 4th, 2019

Early on Thursday morning we were notified by our internet provider, TENET, that there has been a break in internet connection between UWC and SUN. This caused an internet outage on the entire SU network for most of the morning.

Technicians were immediately dispatched to the site and after investigating, established that the infrastructure has been vandalised and the fibre cable cut. Maintenance then proceeded to replace the damaged equipment and restore connectivity. Unfortunately both primary and secondary links were compromised and also had to repair the backup link.

We apologise for the inconvenience and appreciate your patience. During incidents such as these please remember to follow our Twitter feed where we will post regular updates.

IT maintenance

Monday, August 5th, 2019

Over the following few weeks Information Technology will be conducting maintenance on servers and systems over specific weekends and some downtime can be expected. 

Weekend of 31 August: Critical maintenance will be taking place on Saturday, 31 August, from 07:00 to Sunday, 1 September, 13:00. During this period a large number of functions and applications will temporarily be unavailable. This includes, among others, Financial Services; Student Administration Services; meal bookings; ePayments; schedules; password change and eApplications. SUNLearn will not be influenced by this maintenance.

Weekend of 6 September: Quarterly, scheduled maintenance will be taking place from Friday, 6 September 22:00 until Monday, 9 September at 08:00. A wide range of systems and services will not be available during this time.

Due to the extent of this maintenance and the necessity for thorough testing of systems and services the possibility exists for continued interruptions into the new week.

Please rest assured that we will try our best to limit interruptions to a minimum. For inquiries please contact the IT Service Desk at 021 808 4367 or log a request on the ICT Partner Portal.

IT maintenance: Feedback

Friday, July 19th, 2019

During both the weekends of 18 June and 12 July Information Technology carried out essential maintenance on various servers and systems. In both cases we encountered problems which caused some systems and services to be unavailable over the weekend, as well as into the following week. These outages were mainly caused by ageing technology and complex inter-dependencies between systems which make 100% availability difficult to achieve.

All systems and services have since been restored and are all once again online. We realise that disruptions such as these impact directly on the productivity of, and services to, our staff and students and although we try to limit them to a minimum, sometimes complexity has unpredictable consequences. We apologise for the inconvenience during these downtimes and can assure you that we try our best to ensure optimal service.

Update: Services temporarily restored

Monday, July 15th, 2019

Essential emergency maintenance to replace a faulty memory module was conducted on Saturday from 07:00 to 12:00. During the process it was discovered that there are additional hardware problems and this caused several services not to be available.

However, our IT staff succeeded in restoring essential core services on a temporary basis late last night. The final restore and replacement of the faulty hardware will take place at a later stage.

We apologise for the inconvenience. For inquiries please contact the IT Service Desk at 021 808 4367 or log a request on the ICT Partner Portal.

IT EMERGENCY MAINTENANCE: UPDATE

Sunday, July 14th, 2019

Essential emergency maintenance to replace a faulty memory module was conducted on Saturday from 07:00 to 12:00.

During the process it was discovered that there are additional hardware problems on the specific server. Due to the hardware failure several services are still down. We are currently working in partnership with our hardware vendor to establish which module is causing failure and will be replacing it as soon as this is known.

We realise that the current situation is inconvenient and apologise for the unavailability of services. Rest assured that we are doing everything in our power to restore all services as soon as possible. For inquiries please contact the IT Service Desk at 021 808 4367 or log a request on the ICT Partner Portal.
