Your Pages Timing Out

Some servers have bandwidth restrictions because of the associated cost that comes with a higher bandwidth; these servers may need to be upgraded.  Sometimes, the issue is hardware related and can be resolved by upgrading your hardware processing or memory limitation.  Some sites block IP addresses when visitors access too many pages at a certain rate. This setting is a strict way to avoid any DDOS hacking attempts but it can also have a negative impact on your site.  Typically, this is monitored at a page’s second setting and if the threshold is too low, normal search engine bot crawling may hit the threshold and the bots cannot crawl the site properly.
Solution is, if its a server bandwidth limitation, then it might be an appropriate time to upgrade services.
