Compare:

• x/build: linux-amd64-wsl builder runs into "unexpected EOF" errors downloading dependencies #54275
• all: test failures using non-golang.org proxies #55163
• all: test failures using proxy.golang.org #55162

[bcmills]

Per #54275 (comment), the unexpected EOF failure mode generally indicates that the server declared an explicit Context-Length but the response returned by the server for some reason did not match that length.

[heschi]

It seems like this is pretty rare so we'll leave it low-priority for now. If that changes we can take a look more urgently.
