Do you offer one year free hosting for student accounts from outside the USA? I've tried to register (as a teacher, trying things out on behalf of students) using an email account which ends .edu.sa - this was rejected by your system. Thank-you for any advice you can offer.
The effect is to restrict student accounts only to the USA or the small number of countries that register schools in the American way. Most don't. For example, UK academic addresses end with .ac.uk and Saudi with .edu.sa
Other ISPs check for .ac.uk specifically, and for .edu anywhere in the address. They get the business and perhaps the future influence. InterServer doesn't / won't.
