Hello,

Following our previous communication regarding the v3.2.0 upgrade issue on hosts with limited disk space, our records indicate that some of your resolvers may still be affected by disrupted DNS blocking or high CPU usage.

We’re seeing a temporary upstream issue in Docker’s package repository where the containerd.io package referenced by apt is unavailable (404). This can cause new installations of our resolver stack to fail when installing Docker (and may also affect apt upgrade on hosts using Docker’s apt repo).
