Interesting read. It seems to me some of the long tail risks mitigated by expensive redundancies might be an acceptable risk for the customers. For example, the article indicates that they have redundant power suppliers, along with 2 days worth of diesel for on-premise generation. Apparently keeping the second power company available is a recurring cost. What are the chances power is cut to the office for more than 2…
There are limits on how long you can keep your generators running without causing mechanical damage - hence two generators.
Redundant power company only charges for usage, there is a small recurring fee for connectivity. If Power goes out from one provider, online UPS kicks in - we switch to secondary power-company if there is a long downtime.This happens about 4-5 times a year - longest blackout was 12 hours to the best of my recollection.
When you provide internet service for SME, Banks, and some large-scale corps - redundancy and SLA plays a huge role. Home users benefit from this too.
I probably should have been more clear.
