Because they closed a service? I think you'll be hard pressed to find anyone - company, non-profit, whoever - who will maintain a service indefinitely.

If you want to keep something running for as long as possible, you need to eliminate single points of failure like those (except yourself, of course). That means building a stack where each part is either ran by you or a replaceable commodity.

For example, I run my email, RSS and website on a generic VPS (of which there are many providers) which runs an open source stack that I know how to configure and maintain.

I still rely on other people, but not on a single person or company.
