Our documentation for rolls can be found here: 

https://sites.google.com/a/google.com/chromeos-toolchain-team-home2/home/toolchain-info

in particular, for binutils, see "Rolling Binutils Changes".

also, in there, we have

"Post steps for toolchain roll"

and from the main page we have:

"Toolchain team testing guidelines". 

All of these need to get updated to:

- Make sure that before toolchain roll, testing results are "peer reviewed" to make sure we are not missing real failures from the testing.
- Make sure that documentation about the updating/reverting binutils is correct and up-to-date. (for ex, revert should be chumped after a successful CQ run).
- Mention what is a good timing for the roll (dont do over weekends).
- how to prepare for a roll back.

Initially assigning to Rahul to address the concerns from the last failed binutils roll.
