High uptime is not something to brag about for a tor node, so don't worry about that. If you're running a debian-based linux distro, you can have unattended-upgrades[0] do the work for you and warn you via email. There are tools that will allow for similar workflows for other OSes, eg. with dnf on rpm-based distros[1]. > Secondly how long can a relay be down before flags are dropped? > I don't know the upper bound, but twice I've migrated keys from an old piece of hardware to a new piece of hardware when the support warranty expired, and that node still has the stable flag. I took my time and did the migration carefully. It's far more important that you follow the advice[2] on how to keep your relay in good shape once it's up and running than that you find the limits of certain flags.
