Reactivate your network access before 1 April

Thursday, February 20th, 2020

Network access for staff will expire at the end of March unless you reactivate your username.

We suggest that you reactivate yours as soon as possible to ensure uninterrupted access to IT services (internet, email, SUN-e-HR etc.). Keep in mind that the cost centre manager still has to approve your request before your username is reactivated; allow sufficient time for this to be done to avoid disruption of your service.

You will receive an email from helpinfo@sun.ac.za indicating that your username (“engagement”) will expire soon. Three notifications will be sent before the end of March. Alternatively, you can go directly to the reactivation page.

Once logged into the reactivation page, you can select the services you want to reactivate.  You are encouraged to read the ECP (Electronic Communication Policy) before reactivating.

Choose the services (network / email usernames and internet usernames) you want to register for (see images below).

 

 

Make sure you select the correct costpoints and if you’re unsure ask your cost centre manager. Click Accept and Reactivate.

 You will receive a notification stating that your request has been submitted, as well as a confirmation email. 

The webpage will indicate that it will be activated as soon as it has been approved by the cost centre manager. When the cost centre manager approves the reactivation request access will be extended to the end of March next year.

If you have completed these steps successfully and still receive emails from helpinfo@sun.ac.za urging you to reactivate, please go back to the reactivation page and make sure the appropriate boxes are checked: Your Network / Email usernames Your Internet usernames

 If you are still not able to reactivate, please raise a request at servicedesk.sun.ac.za

Residence WiFi renewal project

Monday, February 3rd, 2020

Over the past two years Information Technology’s network infrastructure team worked hard at ensuring that all SU campus residences are equipped to provide effective WiFi network access to students.

As the project is drawing to a close, we can recap and provide statistics.

Nearly 1500 WiFi access points were installed of which 571 over the December/January holidays. The last, outstanding WiFi hotspots will be installed during the June/July holiday time period.

The following number of WiFi hotspots were installed over the holidays:

Stellenbosch campus:

Huis De Villiers               67

Dagbreek                          89

Metanoia                          186

Huis McDonald               37

Helderberg installations will be completed at the end of February while Minerva is scheduled for the June 2020 slot. Due to construction at Goldfields installing WiFi points wasn’t possible, but is scheduled for when construction is completed. For more detail on current WiFi coverage on Stellenbosch campus, see below.

Tygerberg campus:

Franci van Zyl                  67

Hippokrates                     78

Elective students            15

Effect of internet cable break on Stellenbosch University

Monday, January 20th, 2020

The recent internet speed problems that South Africans have been experiencing has been front page news since mid-January. How has it affected the University community?

The short answer is that in most cases, we don’t see any degradation in network performance at all. How is this possible, one may ask? The answer lies in the redundant design of our international circuits, as implemented and managed by TENET, the service provider for the tertiary education sector. When a particular network circuit is broken for some reason, like the West African cable (WACS) in the current situation, the university traffic is seamlessly re-routed via another circuit, Seacom, running along the East Africa coastline. Obviously, the risk of total network failure is enlarged by the current unavailability of WACS (and SAT3), but up to now our services remained available without a hiccup. This can be seen from the following graphs, which show constant traffic flow for the past week, 100% interface availability of the network, spare capacity available and zero network errors reported.

Other network service providers often don’t have this level of redundancy available, and may be more seriously affected. That is why ISP’s like Axxess, Afrihost and others have been struggling, and why some users might have experienced communication problems at home, or while using other networks other than the campus network. 

When will this situation normalise? The WACS cable on the coast of the Congo is currently being attended to by the cable repair ship and TENET’s estimation is repairs could be completed by 11 February.

For regular updates and information on how the repair process works, follow TENET on Twitter.

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.
