Re: With all due respect
I rarely need to get support from vendors of on-prem hardware or software (including email servers). I supply stuff that, if it breaks I can fix without needing outside assistance. There's a lot of people out there selling stuff that they can not support by themselves (and this, by definition, includes The Cloud). This is one reason I do not like The Cloud: regardless of your resourcefulness at fixing On Prem nasties, you are up against a brick wall when trying to get to the root of a Cloud problem.
If the problem is the Broadband then that is a fault common to both Cloud and On-Prem. Ditto DNS issues.
