Please contact your web host provider to see if they are having server issues. If you pause your website campaign and your site goes back up, it is likely that the web server you are using cannot handle the amount of traffic it is receiving from the campaign. You can either upgrade your web server or try lowering the maximum hits per hour in the settings so that your website does not get overwhelmed with visitors we send you.
Some early signs that your site might be having downtime are: hijacked pages, pages that don’t load and slow load times. Some causes could be operator error such as deleting files you weren’t supposed to or forgetting to renew your hosting plan/domain name. Another reason could be that your server cannot handle the amount of traffic you’re receiving or that you’ve reached your monthly limit in bandwidth that your web host provider allows. It could also be that a hacker hijacked your pages or has DDoS (distributed denial-of-service) attacked your website. It can be a headache determining what’s causing your site to crash but remember that whatever it may be, always stay calm, contact your web provider and find solutions to fix and prevent it from happening again.
