Issues running Chromium/puppeteer/codeceptjs today

Hey, is anyone else seeing issues with automated browser based actions today?
As of about 8 or 9 hours ago our hourly checks that run on github actions seem to freeze when we start up.
Looks similar to when we run on other machines but with not enough memory, wondered if maybe there’s some new memory limits or something added today?
(No code changes our side to those actions for months before the issue started).
Thanks.
