Fri 06:36 SEACOM stable, WACS will require a maintenance window to replace a controller card at the London POP.
Thu 19:50 Update, SEACOM link is restored but WACS still down.
Thu 19:25 There is currently a dual SEACOM and WACS failure.
The emails below were forwarded from SANREN. We will keep this blog and our dashboard updated as we hear more.
=====================
Dear All, WACS services were temporarily restored at 22h30 last evening [21/01/2106]. An issue with a controller/communication card at the WACS London PoP caused protection switching to fail. In the interim, a temporary physical bypass of the affected equipment has taken place. A further maintenance window will be scheduled to normalize this route. SEACOM remains up and stable as per the last update. Advisories will take place as and when further information comes to light regarding WACS permanent restoration. Kind Regards Lynette Pretorius TENET Network Engineering (06h36, 22 January)
Dear All,
SEACOM successfully restored the link at 18h45.
WACS outage feedback remains the same. Because WACS is still down, the network is at risk of a similar failure.
Further advisories will take place if the situation deteriorates back to a double international failure.
Kind Regards

Dear All,
SEACOM informed us at 18h22 that their fibre team is busy with link restoration. The ETR at that time was 1 hour to restore.
WACS feedback has remained unchanged since 16h18 with the last status being that the WACS PNOC was working on an interim solution to restore traffic on a protection path.
A further advisory will take place by 20h30.
Kind Regards

Subject: [REN-news] First update [WACS and SEACOM both down]
Dear all,
Both failures appear to be terrestrial – the WACS failure is confirmed to be in the UK and the SEACOM failure is reported to be in Egypt. Subsea failures would have been much more worrying as they can take days, even weeks, to fix, whereas terrestrial failures are generally addressed within hours. We accordingly have reason to believe that service will be restored reasonably soon. Notwithstanding this, we’re also investigating restoration options from other providers as a backup.
A further advisory will be issued before 19h00.
Regards to all
