O+M 2024-06-24

[FuhuXia]

As part of day-to-day operation of Data.gov, there are many Operation and Maintenance (O&M) responsibilities. Instead of having the entire team watching notifications and risking some notifications slipping through the cracks, we have created an O&M Triage role. One person on the team is assigned the Triage role which rotates each sprint. This is not meant to be a 24/7 responsibility, only East Coast business hours. If you are unavailable, please note when you will be unavailable in Slack and ask for someone to take on the role for that time.

Check the O&M Rotation Schedule for future planning.

Since 2024-06-25 03:50 EDT googlebot started to send nonsense traffic to catalog, doubling the total requests catalog receives, and doubling the catalog-web CPU usage. If this trends continues, we might have to block certain traffic based on the request pattern. Details in slack discussion.
