Please see some of the other sanral threads in various sections of the forum. There have been some routing issues to SANRAL (on SANRAL's side) since around 30 Dec. Telkom Internet ADSL IPs were affected, but that is now fixed. Telkom Mobile has some IP blocks (at least 197.208/16) that are still affected. Afrihost/MTN's 105.237/16 was affected last time I checked. And, every website availability testing site I tried still shows it as down. It took about 4 days from when we reported it to their service providers to get access from Telkom Internet ADSL fixed.
Maybe when that gets to the news they will claim that they were hacked. Or trying to prevent hacking. When of course, it seems they don't understand routing much ...
