Possible Increase to Origin for Custom VCL Using querystring API

[in progress]
Engineering has deployed a fix and have confirmed a gradual recovery for customers with a custom VCL using the querystring API. We will continue to monitor until we’ve confirmed that customer experience has been fully restored. As this mitigation deploys throughout our fleet, customers who believe their services to be impacted may reach out to our Support team by emailing support@fastly.com. Our team has been provided with workaround that will can be deployed to prevent impact for the duration of our response to this event.All other products and services remain unaffected by this incident.

We have identified an issue with how our systems are processing requests that involve setting querystring parameters from custom VCL using the querystring API. This is causing an increase to origin for requests that have querystring parameters with an empty value.




We are now developing a fix, and will post a new update once it has been fully implemented and we see signs of recovery.




All other products and services are unaffected by this incident.

We're investigating possible performance impact affecting the Content Delivery (CDN) data center.All other locations and services are unaffected.
