Backtesting should be working again.

I apologize for the outage. The incident was caused by a database failover that we handled incorrectly. This was caused by a bug, which we've now identified and will be fixing later today. In the meantime, it shouldn't cause any further issues unless there's another database failover, which is unlikely since they don't happen that often.

It seems the data is corrupt as all my backtests of an algorithm have the same outcome while the code is different

That's very weird. I don't know of anything that has happened recently with the site that would cause that behavior. Can you please reach out to us privately via email to [email protected] or Help → Send Feedback so we can troubleshoot further with you about it?
