We experienced an issue during a deploy that resulted in the Page Speed reports not loading.
Note: All times referenced below are Coordinated Universal Time (UTC).
At 09:26 our dev team deployed a fix for My Pingdom to improve site performance.
Shortly thereafter they noticed issues with accessing the Page Speed reports and started investigating the issue. They tracked the issue down to a minor mistake in the deploy configuration.
Service restoration was reported at 09:50, although we continued to monitor the situation. We saw no impact on Uptime monitoring or alerting, and data was still being collected by the Page Speed reports.
No data is missing from the Page Speed reports as the issue was simply a communication error between the reports and the data available.
