Pardon my rant, but I am frustrated. It seems there is always an excuse with Amazon cloud. Is Google similarly disabled?

Nope.

I wonder how much of Google's reliability comes from service failover and redundancy and how much from very reliable datacenters etc. I'd find it hard to believe that their platform and DCs aren't better than what we have seen from AWS, which could make compute engine a very attractive product.

A lot of it comes from automatic failover. Individual data centers have issues frequently, but if you're using High Replication Datastore then you won't notice it much, apart from occasionally seeing all your instances getting killed and restarted in a new datacenter, which also results in memcache getting reset.

Why is this being downvoted? Is it inaccurate?

If you mean GAE, its even worse...

I can only talk about my experience, but I've had zero downtime with GAE since we migrated to the HR datastore. Development is x1000 harder, but then everything Just Works.

I had used it before the HR, so it might have improved.

At the time It was like voodoo, and you had to triple-check your datastore actions, because they could fail for no reason at the backend.

App Engine's reliability massively improved with the HR datastore, and has gotten even better since the pricing change / SLA guarantee. It's actually remarkably good now, I recommend taking another look.

I thought App Engine was much more reliable when they switched over from the Master/Slave Datastore to the High Replication Datastore.
