I had a experience of a website coded in PHP. that was a student result database site. specially used for publishing national certications exam in my country. the results are used to publish at a fixed date that was pre-defined. So the site got a lot of access request from clinets or searchers. in this situation the site fails to fetch the result for individual requests. why did this happens? that is why i have rised that question!
1. was this occur for low bandwidth of the lines?
2. was this happened for database server limitations??
3. may web server included for this problem?
