Playing AI Dungeon
Timescale Maintenance Issue (@Last Tuesday)
Starting at 12:38am MT, our database provider restarted our database as a part of planned maintenance. While this should have only taken a few minutes, we had a full outage until 1:37am MT when the database came fully back online.
We were doing maintenance in our clusters to make TSDB 2.11 available to all customers. While we were doing that, we were restarting all customer instances during their preconfigured maintenance window. In addition to that we were upgrading software on the nodes where customer databases are running. We usually keep some spare nodes to accommodate the customer instances after they are restarted. Spare nodes were not created in our clusters in a timely manner this time because AWS couldn’t provide us with enough nodes of the requested size, which caused your database instance to wait longer until it was created. We’ve taken measures to ensure, that spare nodes are available in the cluster and this shouldn’t happen further.
We have a larger upgrade in coordination with our database provider that should be completed this summer, which will ensure these types of issues don't happen in the future.
Heroku Connection Errors (@May 13, 2023)
Starting at 6:00am MDT we saw intermittent connection errors that were causing around 50% of connections to fail on the AI Dungeon API. After attempting our own restart and seeing no progress, we contacted Heroku, who we use to host the Latitude API. They responded and the issue was resolved by 6:57am MDT.
We’ve followed up with the Heroku team since this is tracking with 2 other issues Heroku had in the last 24 hours.

Heroku Network Errors Partial Outage (@February 15, 2023)
Our server provider, Heroku, had network issues related to our cluster. They began around 12:17 PM Mountain Time on @February 15, 2023. We were alerted about lower traffic on our models at 12:42 PM and restarted the cluster to clear up the issue by 12:57 PM.
We continue to work with Heroku to limit the impact of these outages for our player base. We have increased the sensitivity of our own alerting system so that we find the issue sooner if it does occur again.

Healthy moving forward, but previously have had intermittent issues with the servers running our AI Dungeon API @September 20, 2022: The Heroku instance running our AI Dungeon API has had intermittent issues since last Friday that keep recurring. The team is digging into why this is happening and working to mitigate. We have reached out to Heroku for more information about the behavior we’re seeing. Update @September 21, 2022: We've identified the intermittent issues this past week as a Heroku open connections limit we have been hitting (even using their largest plan). AI Dungeon is now healthy given Heroku allowing us to bypass their normal limits. I will share more details tomorrow as we finalize the fix.
Action Counts Off + Griffin Outage (@August 25, 2022)
Description of the incident.
And we had another outage (a combination of database and then Coreweave instances going down). Action counts were off for a bit and ads were behaving oddly. We're awarding 200 actions to any impacted players.
Actions moving forward include a retro with the team and open conversation with Coreweave about how we build more resilience into the pod cluster, even with high traffic volumes.
Coreweave Outage (Griffin) (@August 25, 2022)
Our Griffin Pods had issues that didn’t recover even with a restart. Coreweave was able to help us successfully get the pods back online. We'll be working with them to figure out what caused this and how to avoid similar outages in the future.
Database Performance Issues (@August 25, 2022)
9:00 am: Some users are experiencing lag. We are currently digging in. 9:11 am: We've identified the issue related to database performance and are working on a fix. 9:58 am: A fix has been pushed by rolling back a change we made related to the upcoming gold system and scales changes. We will be adjusting given the performance issues before we push this again.

Partial Android App Outage (@August 7, 2022 )
Version 153 of the Android App is installing but the icon isn’t showing for some Android devices. If you haven’t upgraded we invite you not to. We have a new build already waiting on Google to review that a developer worked on late last night.
This was caused by a relatively small package upgrade that worked in local testing but caused an issue with certain devices in production deployment for Google. Frankly we were surprised by this one since Google review is supposed to catch stuff like this which we can’t test without pushing live. We’ve contacted them to expedite this review and looked into any options for rolling back.
Apologies. We will update here once the new version is live. Android players experiencing this issue can play using their mobile browser as an interim solution.
