How many 9s do you think Coinbase has?

2 9s, or 99% uptime? Or is it worse than that?

They are rarely completely offline. But, they've been experiencing all sorts of "minor outages" and partial service degradation. And when you can't trade or transfer between wallets, the fact that their portal is "up" doesn't matter much.

During normal times? Uptime is maybe 95-99% as they're down for maintenance for a few hours every few days, usually during off hours.

During major price swings? About 10% uptime at best. They're almost always down when the price jumps or drops.
