Looks like they have one provider for main and redundant link which should not be the case. Rumor has it that Huawei has cannibalized the previous players like Nokia and Ericson and now control over 70% of the infrastructure. Safaricom needs to re-look into this to spread/mitigate such risks

so many technical 'experts' on forum, i wonder what the true story is now

Found a vert big bundle in my sim, fibre was down, so checked balance *544# and received a message of huuuuge bundle siui FLEX bundles 1150000 valid for a month it's the one am using, wasn't there when i last used modem, balance was 0 and i bought kes 99/- bundle, or was this the stuff being loaded into our accounts jana?

Backups do fail, even when you test them regularly ...Murphy's law. The thing is you are supoosed to have a backup to the backup...some call it disaster recovery...but it is expensive having all these redundancies, even blue chips cut corners considering cost and that capacity sits idle during normal times. Not trying to defend safcom or minimize the scale of damage done to the economy, just talking as a techie who has lived through these sorts of issues.
On another front, CA requiring an expansive explanation is pointless. They should stick to monitoring and enforcing SLAs. Safcom can spin any old story they want about what happened, only the troubleshooting engineers know the whole truth...even Collymore himself could have been served a massaged and spinned story by the techs, smoothing out the very worst of it..or even outright lies..what is he going to do, argue with experts over engineering technicals?
