The deeper you go into the stack, the more reliable things tend to get, the more mature those systems tend to be and the more likely they are supported by SRE who take things very seriously. So if you're having an issue with Spanner, first it's likely not a bug in spanner. If it's an outage, somebody has probably already been paged. But if not, paging someone responsible will be answered quickly and treated seriously. You could've unexpectedly gone over quota on something. More often than not you can alleviate that with temporary quota while you resolve your issue (by reducing your usage, getting more permanent quota or both). A big part of this is that it's a cultural thing.
