HTTP Error 503. The service is unavailable.
In Windows hosting, this error occurs when an application pool for a particular website is stopped or crashed when website exceeds the private memory limit of 250 MB.
This error can be fixed by manually starting the application pool from IIS itself. While you have purchased the Windows shared hosting, you wont have IIS access. Hence, if you face this error, you can contact us either through chat or ticket. After starting the application pool, if the same web request will come (that caused the application pool crash previously), you may face this error again. Hence, rather fixing it each time when you receive this error, we will send you the exact exception that caused the application pool crash so that you can fix your code to prevent its recurrence.
