We will provide updates as necessary.Mar <var data-var='date'> 4</var>, <var data-var='time'>19:14</var> UTC Scheduled - We will be performing a scheduled infrastructure upgrade on our US deployment cluster. During this window, we will migrate our Kubernetes environment from EKS 1.32 to EKS 1.33 ahead of the end of standard support for EKS 1.32 on March 23, 2026. What to expect: This upgrade is not expected to cause any service interruption. However, as with any infrastructure change, there is a possibility of transient errors and increased latency in event processing during the maintenance window. All other regions and deployments are unaffected. We will post updates here throughout the window. Thank you for your patience.

As a result, synthetic variable calculations and updates are delayed, and some dashboards may have experienced slower response times while corrective maintenance is performed to stabilize the platform. The system is gradually returning to normal operation, and we are closely monitoring performance to ensure stability and prevent further impact. We appreciate your patience and understanding.

Synthetic Variables – Increased Latency

Nov <var data-var='date'> 1</var>, <var data-var='time'>15:12</var> UTC Resolved - Summary: We identified an issue that limited the number of active connections to one of our servers. The root cause was a kernel-level restriction on the maximum number of open files (file descriptors), which also affects network sockets. Impact: The limitation caused a temporary reduction in the number of simultaneous connections the server could handle, potentially affecting availability for some users. Resolution: The kernel and system-level limits for open files were increased to ensure sufficient capacity for concurrent connections. After applying the changes and restarting the affected services, the system returned to normal operation. Preventive Actions: We’ve updated our configuration management to enforce higher default limits across all environments, preventing similar constraints in the future. Status: This incident has been fully resolved, and all systems are operating normally.Oct <var data-var='date'>31</var>, <var data-var='time'>13:53</var> UTC Monitoring - We have restarted the load balancer for the UbiFunction module. This has restored the operation in the module.Oct <var data-var='date'>31</var>, <var data-var='time'>13:28</var> UTC Investigating - We’ve identified an issue affecting the UbiFunction module.

Sep <var data-var='date'>26</var>, <var data-var='time'>00:00</var> UTC Resolved - Incident window: September 25, 2025 – 7:00 PM (UTC-5) to September 26, 2025 – 4:20 AM (UTC-5) Impact: During the incident window, MQTT subscriptions experienced disruptions that prevented data from being delivered in real time. Devices attempting to subscribe or maintain subscriptions may have encountered failures, delays, or missing data. Resolution: Our engineering team identified abnormal connection behavior that led to message queue saturation within the MQTT service. To restore functionality, queues were purged, affected MQTT clients were reset, and supporting services were restarted. Service was fully restored by 4:20 AM (UTC-5) on September 26. Current Status: The MQTT service is operating normally, and monitoring has been reinforced to ensure stability.

We are: – Uploading the library to a new CDN – Replacing the URL in the HTML canvas widget and Widget plugin module.

[AU DEPLOYMENT] Outage

Mar <var data-var='date'>18</var>, <var data-var='time'>04:00</var> UTC Resolved - Incident Summary: Between 11:00 PM and 4:41 AM UTC-5, some users experienced 404 errors when attempting to access applications deployed in our US region. Root Cause: The issue was traced to an unexpected behavior in our caching mechanism. As part of recent DDoS attack mitigation improvements, changes were made to the cache that inadvertently resulted in these 404 errors. Our apps' cache is set to expire every 7 days, and when the cache expired, the affected applications returned 404 errors. This behavior required manual intervention or periodic tasks to refresh the cache. Resolution: A fix has been deployed to ensure the cache is automatically updated moving forward. We have also implemented additional monitoring checks every 5 minutes to proactively identify and address similar issues. Next Steps: We are exploring additional improvements to further enhance reliability and reduce the risk of similar incidents in the future. We apologize for any inconvenience caused and appreciate your understanding as we continue to improve our systems.
