Sure it can wait. IF it's a problem which could never have been resolved remotely, OR if it's one which can be remotely resolved with no time limit on how long the system can remain in the problem state before the repair attempt is begun.
Now, what about option 3 - a remotely resolvable problem which DOES have a time limit on starting the repair, and which if left unfixed when that limit expires will then transform itself into a non remotely resolvable problem?
