"example.vm.bytemark.co.uk" is still used in symbiosis docs
The example domain "example.vm.bytemark.co.uk" is still used occasionally in documentation text, and frequently in filezilla screen shots. This can be seen at https://www.bytemark.co.uk/docs/symbiosis/website-setup/
The correct example domain is example.default.bytemark.uk0.bigv.io - this is used elsewhere in the documentation.
It might also be useful to explain that long domain as an example of the pattern "<HOST>.<GROUP>.<CUSTOMER>.uk0.bigv.io"
It might also be considered confusing that we're using our own name as the <CUSTOMER>. Less confusing if it's explained, but it might be better to use a fictional customer name.
