Repro Steps

Install https://github.com/tnodir/fort/. Block internet access to Windows Subsystem for Linux Service (wslservice.exe)

Expected Behavior

No internet connections made unless triggered by my usage or periodic update checks.

Actual Behavior

Multiple connections per minute to Akamai servers for as long as the system runs.

Connections resume after granting temporary internet access to the service, suggesting this is not an update check situation.

Why is this flood of connections happening? What data is being transmitted? It doesn't influence WSL operation at all.

Hi there. We have looked through our code in wslservice and nothing would be generating that traffic. Do you have a plugin installed? (or potentially, something is thread-injecting into this process)

If you share a dmp of wslservice.exe, we can see.
