Recently a SAT-3 and WACS submarine cable malfunctions that slowed the Internet in Angola. On 16/01/2020, several interruptions were reported in terms of Internet services at submarine stations and submarine cables along the West African Coast. Countries like Mauritania, Côte d'Ivoire, Gabon Congo and Angola were affected.
Each country had a “Hit ratio”, That is,“ impact ”with greater or lesser criticality. In the morning in Angola it was more critical because apparently both SAT-3 and WACS had problems
What really happened?
Following the introductory note and looking from outside the country, it was possible to notice that at around 9:46 am on 16/01/2020 only Gabon and Congo countries closest to Angola and located on the West African Coast were affected as shown in the image below.
Throughout the day after further monitoring using “Oracle Intelligence Tool”It was possible to see in picture 1.1 (taken at 11:15) that Côte d'Ivoire had an impact of 0.3%, Angola already appeared on the map as one of the affected countries and impacted by 0.6%, and the criticality in the Congo and Gabon (Compared to the previous image).
Another catch made around 12:23 shows that the problem has spread and Namibia has become part of the affected countries along the coast with a “hit ratio”, Ie impact of 4.7%, minus 4.1% at the same time as Angola in image 1.1.
- SAT-3 submarine system cutoff;
- WACS problems in the subsea system? Problems at underwater stations?
- Clearly, Congo appears to have a problem with greater impact than other countries in the region;
Large Scale Problems
Knowing that the country has (3) subsea systems where (1) ends in Cacuaco and is managed by Angola Telecom and the other (2) ends in Sangano and are managed by Angola Cables is "CRITICAL" look at the following points:
- It is essential to enter a new submarine cable in Angola and to end it in Cacuaco / Angola Telecom (examples: ACE, SIMBA and or EQUIAN);
- The answer to point (2): At this time Sangano is well-served in terms of mooring submarine systems. Problem is the land routes from Luanda to Sangano that despite being redundant fibers the path is the same.
Imagining that there is a serious problem in the Kwanza bar - it will be impossible to reach WACS & SACS.
- Sequence of point (2): So if one of the above cables is tied in Cacuaco we would have full redundancy in subsea systems taking into account the “lifetime” of the SAT-3 compared to the remaining years to reach the obsolete level.
Things to keep in mind:
- The lifespan of an underwater system ranges from 20 to 25 years;
- The SAT-3 / WASC / SAFE was implemented in 2001 - therefore 19 years of actual use and approximately 6 years of remaining service life. "And we all know how time flies."
- Entry of a new subsea system (very high priority);
- Information and data hosting “LOCALLY” (very high priority);
- Ground links to neighboring countries South, East and North (very high priority);
- Use of SACS by regional operators in southern Angola (Namibia and South Africa);
- Regarding point number (2) there are already local cloud services such as: AZCloud of Multipla, ACloud Angola Cables, ITACloud; Mstelcom Cloud etc ..
- Following the above point it is important to mention that even business of Startups who have your information and or websites hosted abroad may be having trouble accessing your information;
It cannot be denied that problems of this magnitude can already be avoided, that the above recommendations are taken into consideration by decision makers as well as companies operating in the Angolan market to serve end users well.
