Chicago Browser Fail

When using WPT the past couple days, every test (regardless of client domain I try testing), if I use the Chicago, IL servers / Chrome DSL emulator, it says the test completed but failed because it couldn’t load the browser.

When I switch to your Denver server, it works fine.

HELP! I rely on WPT religiously for my audit work and use multiple test locations.

The testing completed but failed.
Timed out waiting for the browser to start.

I am on a Macbook Pro, using Firefox
