The http errors make me suspect a local http proxy/firewall. We've seen similar errors in the past where disabling some antivirus or firewall fixed the mangling of http test traffic.

Hi Brad! I ran all.bat again with the firewall and my antivirus software disabled but I'm still seeing the same test failures.

[bradfitz]

Maybe the firewall is "disabled" and trying its best not to modify or judge traffic but its hooks and buggy interception are still active, thinking they're inert but failing to be transparent. I don't know.

Which antivirus is disabled?

/cc @alexbrainman

[dajoo75]

ESET Nod32 Antivirus, v8.0.312.3

[bradfitz]

Could you entertain me and uninstall it, reboot, and try again?

[dajoo75]

On it.

[dajoo75]

After uninstalling Nod32 and disabling the firewall all tests but one now passes:

What is your machine's timezone? That might be a real bug.

[dajoo75]

$ tzutil /g
W. Europe Standard Time

Too late for Go 1.5.
