Bug 291389 – Tools/Scripts/bisect-builds broken because host fails to resolve

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

Invoking the script gives the error below, which suggests DNS is not resolving correctly the endpoint q1tzqfy48e.execute-api.us-west-2.amazonaws.com

I noticed https://github.com/WebKit/WebKit/commit/d1cec7e0e0bf0db39054a72f762cefe5f2f7c04a, which replaced that endpoint with https://archives-list.webkit.org/ in a different script. I tried to use the same replacement but that causes bisect-builds to hang

When replacing with https://archives-list.webkit.org/, this is where the code hangs

Thank you for the report! We'll look into making this script work again.
