TENET are currently seeing errors on it's SEACOM circuit, which may be affecting international Internet traffic. We've been informed that SEACOM will be performing some diagnostics on TENET's Internet link between midnight and 2AM tomorrow morning (26 April), and this will necessitate an international Internet outage.
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.
