I self host as well as use bitwardens service.

I pay $10 a year, and never have I had access issues with it.

My self hosted instance houses everything for my other self hosted services.

I can also have my Bitwarden duplicated to my self hosted instance.

However, the only way to access my Vailtwarden instance is via my network. And for my use case, this is perfect.

Neither of them have I had any downtime; like others have said it’s anecdotal.
