eseidel@google.com and eseidel@chromium.org (@chromium used to work), also just had issues:

Maybe something changed that we no longer valid committers?

Robbie says Aaron is the right person to talk to.  Happy to perform whatever steps are necessary from our end!

Yes, two announcements were sent to chrome-infra@ regarding the change, which is detailed in this doc [https://docs.google.com/document/d/1NM1D7jrTyi0BeHFyvwq1_d_ESr0Rhnuvw5JWqdVDLDE]

We pruned the committer list, because it previously consisted of literally everyone who reported to Linus as of two years ago. It hadn't been updated since then, neither to add people nor to remove people. And a list that large was obviously absurd in the first place. So it was cut down to a reasonable set of people.

We now follow the same process as Chromium for granting the committer bit: send an email to chrome-infra+committers@ and get two +1s from other committers.

Thank you for the clarification.
