2024-09-16 - TracCloud SAML logins failing beginning at 1:08pm, TracCloud down at 1:40pm, both resolved at 2:18pm MST.

We wanted to inform you that the system issue experienced today has been successfully resolved. While Amazon Web Services (AWS) does not always provide direct notifications for hardware-related issues, we have identified that the root cause was likely a hardware fault affecting systems in one of AWS's availability zones in the region TracCloud resides in (Zone A). This issue impacted several unrelated systems that were all using resources in that zone. Upon realizing this, to resolve the problem, we manually redirected operations to a different zone (Zone B), and both TracCloud and other associated systems are now functioning as expected. We are also in contact with AWS for further clarification, but at this point, the issue has been fully addressed.

2024-09-12 - TracCloud periodically running slowly between August 29th and September 12th.

We wanted to provide you with an update regarding the web performance issues some of you may have experienced between August 29th and September 12th. We understand the importance of reliable service, and we apologize for any inconvenience this may have caused.

Over the past three weeks, we encountered a convergence of technical challenges that impacted our web performance: 1. PHP Unserialization Bug: We discovered a complex bug where PHP unserialization operations were consuming 50-100% more CPU cycles after upgrading from version 8.3.10 to 8.3.11. This unexpected increase in resource usage led to slower processing times for certain functions. 2. RDS Performance Degradation: Our primary RDS instance exhibited unexplained performance degradation. Despite normal operational metrics, the instance underperformed, affecting database response times. 3. Index Changes and Aurora RDS Compatibility: Recent changes to our database indexes affected Amazon Aurora RDS differently than our on-premise MySQL version, despite their advertised compatibility. This discrepancy resulted in suboptimal query performance on the Aurora instance. 4. Shifts in Traffic Patterns: We observed a shift in traffic patterns prioritizing higher-load-inducing requests. Coupled with a natural increase in traffic due to the start of the fall semester and an expanding customer base, our systems experienced additional strain.

Actions Taken: We have addressed each of these issues methodically:

• PHP Optimization: Our development team isolated and resolved the PHP deserialization bug. We implemented optimizations to reduce CPU usage back to expected levels.

• RDS Instance Investigation: We initiated a thorough investigation into the anomalous RDS instance. To mitigate immediate impacts, we have removed this instance from our cluster while we continue to analyze the root cause.

• Database Index Adjustments: We modified our indexing strategy to better align with Aurora RDS's performance characteristics, ensuring consistent query performance across both our cloud and on-premise databases.

• Enhanced Benchmarking Tools: We've improved our benchmarking systems to more accurately track query performance before changes go live. These enhancements will help us identify potential issues earlier in the development cycle.

• Resource Scaling: In response to increased traffic and load, we've scaled up our resources to maintain optimal performance levels.

Our Commitment to Reliability: We continuously monitor thousands of metrics and deploy hundreds of sensors across all TracCloud systems to track performance in real-time. While challenges can occur, this extensive monitoring enables us to swiftly identify and address issues. Rest assured, each time an incident happens, we implement measures to prevent it from happening again, strengthening our systems for the future.

Moving Forward: We are committed to providing you with the highest level of service. The steps we've taken have stabilized web performance, and we will continue to monitor our systems closely. Our team is also exploring long-term solutions to prevent similar issues in the future. We appreciate your patience and understanding during this time. If you have any questions or continue to experience any issues, please don't hesitate to reach out to our support team. Thank you for your continued trust in our services.
