# Maintenance

Although forkless upgrades largely allow for upgrades without needing to change the node software, every once in a while, chain upgrades will break the client binary and require manual updating.

You can (and should) notify the network your collator will be offline for more than 6 hours by running parachainStaking::goOffline() from your collator account.
Conversely, once your maintenance concludes, re-add your collator to the active set with parachainStaking::goOnline()
