Would traveling to the past in order to put in place a preemptive fix for this outage be wise or dangerous?

Asking for a friend.

Tell your friend that this course of action failed, as us in the present are still experiencing issues.

Very unproblematic. Your travelling back will land you in a freshly branched universe with no way back to the one you came from, so no worries there.

I couldn't comment on the causal hazards but since time is currently having an outage they've got an improved shot at getting away with it. I say go for it.

Safety not guaranteed.
