About 15 minutes ago, all South African higher educational institutions lost access to the international Internet as a result of a fault on the SEACOM submarine fibre optic cable.
You will likely experience this outage as an ERR_DNS_FAIL or ERR_CONNECT_FAIL error when trying to access websites hosted outside South Africa (even those ending in .za). When accessing secure (https://) web sites, your browser may report that the connection has timed out or the site is unreachable.
This is likely related to the ongoing problems with SEACOM.
