Throttling override in Office 365
This is in regards to the throttles mentioned here,
My suggestion is, have these throttles in place as default. But for services hosted only in Azure (effectively making you safer from DDoS), allow a tenant wide permission level that gives you much higher throttle limits. Also Azure will block all requests > 1 minute, so keep that in place.
There are many scenarios where the 1RPS throttle is just too too low.
