Ugh. This is why you don&#x27;t build on proprietary stacks like this. I&#x27;ve detailed tonnes of complaints I&#x27;ve had about the platform itself being awkward and buggy in previous HN comments, but this is obviously the #1 reason not to.<p>If Facebook can shut down a service this big, Google or Amazon can too. Moving a VM is (reasonably) easy, but porting an app from proprietary backend X to another is hard.
