My most important site on my network (network is at bhshosting.com) has disappeared!!!

My multisite network (network root domain: bhshosting.com) appears to have lost one of my sites. I suspect a database issue. The site is siteid=11 and is myfitcode.bhshosting.com with domain myfitcodeapp.com mapped as the primary domain for the site. The content is still in the site uploads folder on the AWS server instance. However, WPMU is throwing a site not found error. Other sites on the network are fine although the overall network is slow compared to my other WPMU network on another AWS instance. I appreciate the help!
