We have a server on CentOS 7.4 which runs multiple websites and subdomains.
A domain say xyz.example.com
is pointing to xyz folder in html root which is working since last 4 years and suddenly stopped working yesterday night and is now showing the Apache landing page.
Here is what I tried so far,
- Checked httpd.conf file, and no change has been made to this file since last 2 months
- Checked directory for files and all the files are present, no file has been modified
- Checked for DNS records and A record is pointing to the same IP
The other websites and subdomains are working perfectly fine, but only this subdomain stopped working.
Note: Due to an online event yesterday, that subdomain had heavy traffic.
Any help would be appreciated.
Thanks
