All these things can happen at a centralised hosted solution which is fundamentally more vulnerable because of its centralisation.
The whole point of decentralisation and having 20 witnesses and 100+ backups is that there is a quick failover to the next witness.
Also, for each witness having HEDT servers each with a once off capital cost of $2000 rather than an annual cost of $2000 forever means you can have more backup nodes and more redundancy.
It simply does not make sense to be renting when you can buy for around 1 year's rent.
A server provider usually operates in several countries, so unless someone is cutting an underwater internet cable, a witness can reactivate their server within 24 hours (much less if he/she is more experienced).
While a server in their home/office can easily be shut down for 3+ days, if their ISP is shitty in their area.
If there was an infrustrcture to allow witnesses to share their servers with each other (if that's even possible), to could allow more decentralisation without the drawbacks I meantioned. But I don't know how feasible such a project is.

I’m not suggesting no redundancy. A witness should obviously have their backup server node in another location with another internet provider. Also it’s easy to have have a backup internet provider at your home or office. Everything an outsourced provider can do can be done for much less cost yourself when you are talking about single digit number of servers, which is what decentralized solutions involve.
