We are experiencing an ADSL connectivity problem in the Gauteng area. We are still investigating the cause and extent of the problem. Our engineers are dealing with this as critical priority, and we expect to have more information very soon. We are working with Telkom and MTN to ensure that the cause is neutralised in the shortest possible time.
We sincerely apologise to affected clients. We will update as we receive more information.
UPDATE: 8:30 13 March 2013 - The problem has been identified and recitified, we are currently monitoring to identify any further issues. Clients may have a delay in getting back online to due to backlog of authentication requests. We will ensure that our systems cope as best as possible until ADSL services are normalised. Thank you for your patience.
