This is similar to https://bugs.webkit.org/show_bug.cgi?id=271463 for ews. We stopped uploading archives to build master in 276500@main. So, while downloading archives, when download from s3 fails, there is no point in trying to fallback to download from build master. We should make it a hard failure when download from s3 fails.
