In general, paying GH tends to be much cheaper than employing a team of SREs that'll keep your on-prem Git instance up and running 24/7 (esp. including things like backups, disaster recovery, and similar good practices necessary for any enterprise-ready SaaS).
Something tells me that if you can schedule upgrades "outside of business hours", your scale is small (because in a global company, it's always "business hours" somewhere), which makes the cost argument even more prominent.
If you work in a large business that needs git but doesn't have backups and has no disaster recovery plan at all you're going to have much bigger things to worry about than a git repo being offline.

You don't employ a team of SRE's with the sole day-job of git maintenance though, your existing SRE/sysadmin team manages it.
And any large business will already be doing Backups, DR etc for their existing systems.
Any? Are you sure?
Lol don't crush their optimism, the real world will do it for you in due time
Been doing it for 20 years so far.
