Sorry for the inconvenience. We did notify customers about 4 month ago in December that we would be moving away from managed servers and focusing in the API with customers now being able to setup self-hosted options for increased security, handling of sensitive data and customization. (supported integrations here https://docs.moralis.io/#integrations) This was voted by the community as you can see on our roadmap https://roadmap.moralis.io/
Then about 1 month ago we also notified customers over email that we will finally (after about 4 months of the previous notification) be removing managed servers for all plans, including pro-plan, etc, with the option of keeping it for more time paying an extra, but the idea is to self-host, the $99 server is more for emergency purpose. So, this was not a sudden or capricious change, it was well thought for the benefit of our customers and our business at the same time and timely notifications where send so that customers could migrate their systems with no impact.
We recommend to check our email notifications for this kind of critical change within enough time and there should not be any problem in the future using our system. I don’t believe we will be making any major changes soon but if there are any, we will also notify with plenty of time for smooth transitions. This is a reality of almost any computer system, updates are needed from time to time and as long as they are implemented in a timely manner there is not problem. If you need any other help in this transition please let us know, we commit to provide the best service.
