Upstash redis connection errors

I’ve been getting intermittent connection errors when connecting to my Upstash Redis instance. I’m connecting using Python and get the following error:

redis.exceptions.ConnectionError: Connection closed by server.

I have been using the same Redis instance for a few months and haven’t had any issues. This connection issue started about 16 hours ago.

According to the Fly CLI and Upstash dashboard the Redis instance is fine. I have restarted my Fly machines but that hasn’t helped.

Is there any other way to debug the Redis instance so that I can figure out what’s going on?

As far as I can tell I’m not going over any of the limits on the instance (Redis by Upstash · Fly Docs).

We are seeing these issues on every app across multiple orgs with our uptime monitoring.

Connections are dropping for 1-3 minutes repeatedly for the last 24 hours.

{"redis":"Exception: Connection lost (ECONNRESET)","status":"ERROR"}

Hey @snopoke @danwetherald
Upstash team is here!

Do you still encounter the issues? We had some upgrades yesterday and found some glitch in the server configuration that might drop the connections time to time.

It should be fixed now. Can you please confirm?

We will take necessary actions in order to prevent this happening again.

Hi @bi1 - We were seeing issues the last 24 hours, but it has been 4 hours since the last incident.


Thanks, resolved on my side too after a machine restart.

Great! We are closely monitoring.
