Back at the end of February Draw.io announced that at some point in 2020 they would be moving to diagrams.net.
Well they are now diagrams.net. The post on their website gave the following reasons:
There are two major problems with .io domains:
- The first is that the islands which should own the domain suffix, don’t, thanks to a wonderful piece of modern day British Imperialism. If you ever feel the need to donate to us, please give it to a more worthy cause.
- Secondly, there was a security issue with the .io domain. In 2017, a researcher managed to take control of four of the seven authoritative name servers for the .io domain. We accept that mistakes can happen, strong processes limit the chances of them happening, but they still can.
I would say if they want to sell the name there would certainly be some domain investors that would be interested at the right price.
They probably need to use the redirect for awhile til everyone is familiar with the change. Buy maybe one day.
