“Unfortunately a problem occurred immediately after commencing the planned maintenance and this resulted in all live ADSL sessions being ‘reset’; commencing approximately 15h49.”
Can't be. Mine died, according to my DSL logs, at 15:15:57. I had emailed support (not knowing the cause of the problem) at 15:40.
Planned maintenance gone wrong.... something only Telkom can get right![]()

Not actually - planned maintenance in the IT world is one of the most vulnerable times. Unfortunately, the complexity of our IT systems means that anytime you change anything you face the reality of an unforeseeable breakdown.
Reality of IT systems - it ain't pretty behind the scenes.
Did you not read the article? It is considered non-invasive maintenance that doesn't affect customers and happens on a regular basis, ie. it can be done during the day when you have most of your staff on hand.Why did they not do the planned maintenance after business hours or during the weekend?
Im pretty sure the part that isnt mentioned is that there was some human fault in all of it. Someone issuing a disconnect by mistake or something along those lines. It happens all the time in IT and gets blamed on "something went wrong with the system"
Still it didnt take that long for the radius to pick up and start getting people back online. The load must have been massive though, I cant recall any time where this has happened on such a large scale in the past.
As a matter of interest whilst 10210 faults died the SMS fault report system was running. Scary actually as I now have a fault number and, knowing Telkom, I can expect some disconnects before someone phones to clear the fault.
