This article title piqued my interest but in the end it lack some key pieces of info I would need to try.
This also feels lacking to me. How does one order a DNS instance from DO? I can tell from the icon that it has something to do with CentOS but I don't see any sort of DNS server under their available applications or images for a one-click install.
It seems based on my recent trial experience with CloudFlare that both CDN startups might have this issue of incomplete/insufficient instructions and information for their users/customers to properly implement the solution and lot of assumptions about the skill level of users implementing the solution.
Actually, I landed up providing detailed instructions to CloudFlare on configuration and testing of their service. And a list of questions, answers to which should be readily available if CF is targeting enterprise customers.
"We setup DNS info to point here (both NS1 and NS2..."
That's great, but it would be nice to see:
"Using the geodns web-based configuration tool, we setup DNS info to point here (both NS1 and NS2..."
or
"Running <insert full command line here including tool and all options used here> on <insert environment here>, we setup DNS info to point here (both NS1 and NS2..."
or
"By editing /etc/<file> on the <some environment>, we setup DNS info to point here (both NS1 and NS2..."
In other words specifics are always really great to include.
But still this was a really great writeup, not just for the overview it gives of one lightweight approach but for the comments it has kicked off.
