@steeve, @changkun: was this caused by a configuration change? (If it has been reverted, perhaps run retrybuilds to clear the failures?)

[changkun]

I think so. Somehow for unknown reasons, corellium removed all of our builders for iOS and one of our Android builders. Yesterday, I restored the environment following the instruction here. However I am not entirely familiar with the requirement for Android builders. It seems that this step does not setup clang properly: https://github.com/golang/build/blob/61db2df4c25c3e91cd93724630a44223de10a44e/env/corellium/android/install.sh#L47

I will investigate this soon (hints are also appretiated).

@changkun sorry to hear that, is this something that happen often ?

It is very often (approx. biweekly) that builders are somehow being stopped (hence unreachable), removing the builders happened twice (including this time). I queried Corellium customer support, they still don't have a response to that.

Ok, I'm going to reach out to their CEO, hopefully that bumps the priority.
