I've spent a few hours reading SCPs so now I really have no idea what the hell an anomaly would mean in this context.
Just a small computer glitch or, things firing/smoking when they shouldn't, or something more drastic?

Things firing/smoking when they shouldn't? That's an anomaly too.
Pressure reading slightly out of predicted range? Also anomaly.
Everything went kaboom? That is also an anomaly, as long as that wasn't the plan.
Basically everything where expectation and reality do not meet.
