2021/12/14 - Scheduled electrical maintenance, 14-15 December
Updated, 13 December, 15:00: On 14 December 2021, electrical maintenance will interrupt power to all parts of campus on the western side of South St/Rhodes Ave.  On 15 December 2021, electrical maintenance will interrupt power to a large area of campus.  The affected area is from African St to Beaufort St (including Winchester House) and from Somerset St to South St/Rhodes Ave (including CPU, Dingemans and Psychology Clinic). The notification from Electrical Services is on toplist. The impact on network services will be: In each area, provided all of the necessary generators are operational, buildings which do have access to generator power will have access to network services. All buildings in each area which do not have access to generator power will not have access to network services (including Wi-Fi and telephones). Buildings outside of the affected area on each day will have access to network services. All services normally accessible from the Internet will continue to operate.
2021/12/01 - Card-based access control migration, beginning 1 December [update 9 Dec]
Starting from the evening of 1 December, the staff/student card access control system in the buildings listed below will be migrated to new server software. From that time, existing cards will provide access as before, but it will not be possible to issue new/replacement cards or grant additional access to existing cards. During the course of the week of 6 December, it will be possible to issue new cards, but they will only be usable on buildings which have completed their migration to the new software.  That process of migrating each building will begin on 6 December, though it is not yet clear how long it will take to migrate all of the buildings to the new software. Affected buildings: Africa Media Matrix Struben Building Geography Building Hamilton Building Biko Building Health Suite Physics Building New Arts Building Eden Grove Building ELRC Chemical and Pharmaceutical Sciences Building Library Life Sciences Building School of Languages Education Building Theatre Building 5 Prince Alfred St Update, 9 December: We are in the process of migrating the old P2000 access control system to a C-Cure access control system due to end of life of the P2000 system in January 2022. The process requires some hardware installation and cutover. The process began on Monday 6th December. Unfortunately the team has been hit by Covid and quarantine requirements. Buildings that were to be migrated this week will be done in January. The Library, Struben and New Arts are complete. The remaining buildings below will still have access control working but no new cards can be added to the access control database until the migration is complete.

All IMAP mailboxes will be set to read only. Existing messages in mailboxes will still be accessible, but it will not be possible to move messages into IMAP mailboxes. Access switches: software will be updated on the network switches in the buildings listed below.  All network services (including Wi-Fi and IP telephones) may be disrupted in those buildings for up to 30 minutes. 19 Somerset St 4 Gilbert St 5 Rhodes Ave Adamson House Allan Gray House Allen Flats Amina Cachalia House Atherstone House Beethoven House workshops Beit House Botany (front Schonland Building section only) Campus Protection Unit HQ Canterbury Annexe Celeste House Charlotte Maxeke House Chris Hani House Confucius Centre Continuing Education Centre Cullen Bowles House De Beers House Drostdy Lodge Ellen Kuzwayo House Enoch Sontonga House Fine Art Photography Goldfields House Guy Butler House Helen Joseph House and Annexe Highway Africa Building Hilltop 7, 8 and 9 Houses Hilltop Hall admin block ILAM Joe Slovo House Library (certain L3/L4 areas only) Lincoln House Livingstone House Margaret Smith House New House Oakdene House Olive Schreiner House Oriel House and Annexe Prince Alfred House Robert Sobukwe House Royal Engineers Building Ruth First House Sisulu House Stanley Kidd House and Annexe Stockenstrom Place Thomas Pringle House Victoria Mxenge House Walker House Server software updates: software on the servers which provide the following services will be updated, resulting in outages of up to 15 minutes per server.

2021/11/30 - Scheduled maintenance, 30 November
During the Tuesday, 30 November maintenance window, maintenance work will affect certain services, starting at 5:30 PM and being completed before midnight. The following work is planned: VPN: support for VPN connections using the L2TP/IPsec protocol will be discontinued. If you find that you're no longer able to connect to the VPN service, please configure your PC to connect using the SSTP or IKEv2 protocols by following the instructions for Windows or macOS. PBX: the university telephone system will need to be restarted. We expect that all phones (IP telephones and emergency phones) will be unable to make or receive calls for around 15 minutes. Phones will likely show a message reading "Discover 146.231.128.90" during that time. This work has been attempted a number of times in the past but, due to technical difficulties, and despite support from our PBX support provider and the software vendor, we have not been able to successfully complete it. We will be working with our PBX support provider to attempt the change once again. This work is being conducted during a minor maintenance period. Should there be a compelling reason why this work should not go ahead as planned, please contact support@ru.ac.za before 3:00 PM on Tuesday.
