The MIT CloudDB server is currently offline for users using the default. The default server frequently glitches over weekends and periods of high use.

If you want/ require reliability, please use your own Redis server. The default server is for testing.

MIT has been informed. Perhaps service will return soon. This being Mother’s Day in USA, restoration of service might take a while.


HOWTO: Setup a Local Redis Server for CloudDB

Re: How do I host my website to ’ redis ’ to use CloudDB on AI2?

…and use a FirebaseDB instead of a CloudDB. The FirebaseDB runs on Google’s servers. It uses Blocks with similar functions.


CloudDB should be back. Sorry about that. It’s SSL certificate expired. I have put a new one in place and set a reminder for next year for me to replace it before it expires!


Thank you very much Jeff for your quick response.
