It only takes one month long outage of an international undersea cable to negate all the benefit of SaaS when that SaaS is hosted in or heavily depends on other services hosted in the USA or Europe. DNS goes down for a particular dot com? BGP hijinks? Backhoe through the major fibre serving your workplace? All of these are going to happen and will lead to downtime out of your control or the control of the SaaS provider. Thankfully git is designed to be decentralised and developers can continue to work even if they have to use paper books as reference material and not Stack Overflow.
