Hi Volker,

If you use round robin DNS, you will have the problem that 50% of your
traffic will disappear, when provider 1 goes down. Yes, you could try and
fix this with changing TTLs, but its messy, and browers, and other DNS servers
which are not in your control, may cache things, even though they shouldnt.

For smaller projects, I would recommend going for 2 connections from 1
provider.
