Looking at the console I see:

It appears that the static bundle (https://delivery-console.stage.mozaws.net/static/js/main.712a2b3f.js) has disappeared or somehow the "static" folder is no longer pointed at the correct location.

@sciurus thoughts?

main.1a1cb3a9.js is the bundle from the latest build, but it's not the one Firefox is trying to download. Firefox is trying to download one from the previous build, which the latest build deleted.

bpitts39260:~ bpitts$ aws s3 cp s3:/$BUCKET/index.html .
download: s3://$BUCKET/index.html to ./index.html
bpitts39260:~ bpitts$ grep 'static/js/' index.html

That shows the files in S3 are out of sync. The assets are from the latest build, but the index is from the previous build.

Checking built history, Jenkins has decided to deploy v1.19.0 to stage 6 times!

4/10 16:46 5/10 17:51 5/27 16:11 5/31 10:34 5/31 12:49 5/31 12:50

I believe those last two builds ran their uploads concurrently, which is how we ended up in this mixed state. I've reconfigured Jenkins to disallow concurrent builds for this job, which will prevent this from happening again in the future.

I don't understand why Jenkins is forgetting it has seen this tag and retriggering the build, but I don't plan to investigate this.

I've redeployed stage and it's working again.

I've verified that this issue is no longer reproducible using Firefox Beta 78.0b1 and FIrefox Nightly 79.0a1 on Windows 10 x64.
