You don't see 'Maintenance' on systems of companies which do this for a long time. You might see this at 'normal' companies. Smaller ones who used the 'wrong' database and had to migrate it.
If you start with one database and 'forget' or just don't think about it to have a master, slave, slave combination, you have to fix that once.
When you made a mistake, you have to fix it once.
Also today you are able to maintain quite a big page with a very small amount of people. The chances, that one of those didn't think about all necessary elements of an always online system is not far fetched.
