Bot(s) for this bug's original alert(s):

chromium-rel-win7-single

How do I tell which of the builders on this page: https://build.chromium.org/p/chromium.perf/builders is my test machine? 

Was this machine just deprecated?

https://build.chromium.org/p/chromium.perf/builders/Win%207%20Low-End%20Perf%20%281%29/ returns "Not Found"

 Issue 637955  has been merged into this issue.

Re #2: Yeah, normally you would click the stdio link, which I think is how you got to Win 7 Low-End, which is deprecated.

Great. Thanks for the help!

I added a note to the instructions for triaging data stoppage alerts for seeing if the machine was deprecated. Not sure what the best way to do that would be, but we can discuss on the doc.
