Please be advised that emergency network maintenance work is being conducted on the SAT3 undersea cable by technical teams responsible for its operation. This is affecting many backbone networks and telecoms operators in South Africa that route traffic over this cable. Some customers may already be experiencing higher latency on some routes that are seemingly unrelated, such as local traffic. We have been informed that estimated resolution is Saturday 24 April 2010 at 18h00. iBurst is working to ensure a minimum of disruption to our customers, but as some of the routes are not within our control, we would recommend that customers review any business-critical systems that may be affected.
