Site no longer coming up

Hello,

I created a website last week and have worked on it during the week learning how to create a wordpress site. I finished it last night and everything was working earlier today but tonight when I went to pull it up, it no longer is recognized as a website.

I also tried the wp-admin and it also does not come up. Any thoughts?

I did recieve an email from wordpress today that an update had taken place, but that no further action was needed on my part.

Thank you for your guidence.
