Beginning at 20:17 UTC on February 27, 2025, we identified an issue impacting DNS functionality for newly provisioned distributed Linodes across all distributed regions. This resulted in DNS loss for some newly deployed Linodes in distributed regions. 

After investigating, we determined that the root cause was a misconfiguration in the network configuration, which failed to specify DNS resolvers for newly deployed customer Linodes. This caused the affected Linodes to be provisioned without DNS functionality, leading to connectivity issues for some customers. 

To resolve the issue, we deployed a fix that ensured the network configuration file correctly included the required DNS resolvers. After deploying the fix, we conducted extensive testing to ensure that newly provisioned Linodes were correctly configured with DNS resolvers, eliminating the connectivity issue. We also verified that rebooting affected Linodes would restore DNS functionality for them. We monitored the situation closely and confirmed that no additional issues were observed across all distributed regions. The issue was fully resolved on February 28, 06:43 UTC, after a fix was successfully rolled out.

This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing and any information herein is subject to change.
