Messages like this are only sent if the password was correct, AFAIK. (Google sends the message in part as a warning and in part to explain that no, your password wasn't wrong, they just don't think it was actually you.)
This was presumably not you, so change your password immediately.

Worse than an outage, I got this dreaded email from Google a few hours ago. I hope there isn't some sort of attack going on:
Someone recently tried to use an application to sign in to your Google Account - xxx@gmail.com.
We prevented the sign-in attempt in case this was a hijacker trying to access your account.

I had this today as well. Where was your attempt coming from? Mine was in HK.
(To be fair, I think it was my own machine attempting to connect via VPN)
Got one yesterday from Anhui China. I'm definitely not using any VPN services there
