2010/08/04 - Unscheduled Internet Outage
At about 11:30AM this morning we lost access to the international Internet for reasons as yet unknown. You will likely experience this outage as an ERR_DNS_FAIL or ERR_CONNECT_FAIL error when trying to access websites hosted internationally (including .za sites hosted outside of South Africa). When accessing secure (https://) web sites, your browser may report that the connection has timed out or the site is unreachable.

TENET are aware of the problem.
International access is currently working intermittently.

The problem appears to be between Durban and Mtunzini. TENET have two separate routes between these locations, provided by two different providers. The primary route, provided by Dark Fibre Africa, failed this morning for reasons that are still being investigated. All international traffic should have automatically been re-routed via the second, protection circuit provided by Neotel. Unfortunately this does not appear to have happened properly, and at the moment traffic appears to be switching between the two. TENET, Dark Fibre Africa, and Neotel are currently investigating the matter.

Once they've managed to stabilise the situation, TENET will still need to understand the root cause of the failure. To this end, they've indicated that they may do further testing between midnight and 4AM tomorrow morning and that we'll be at risk of an outage during that period.
