I've had horrible luck with Google's login system. It's very broken. And the ruins of it are scattered across Youtube as well. It's a MAJOR effort for me to login and get anything done. I need to set aside an hour, minimum.

I've got a client that was talked into hosting their Email domain at/with Google. It has been the most unbe-freaking-lieve-able Train Wreck I've ever been involved in. After 6 months the office manager
still doesn't have a working Email address.
Well we just delete the mailbox and recreate it like the instructions say, right? Ha!
Wrong!! Oh sure, you can delete it just fine ... But you'll never be able to create another one with the same Email address ever again. Try to create a different Email and use the first one as an alias for it - HeHe Nice Try - Fail!
From and administrative standpoint, I'd have to say that Google's mail hosting is the most uselessly broken, user hostile, total piece of shit I have ever encountered.
The only thing I'm taking away from the experience (aside from total disgust with the ~Cloud~), is a firm belief that MS Exchange (which has served me flawlessly for many years) is a far better solution...If you really do depend on reliable Email service.
