My Apache server PHP website secured by SSL has been down since last 48 hours. We had a strange issue triggered by Google crawling, which resulted in huge traffic and utilization spike. Since then, our website has not gone back to normal even though we have upgraded capacity, etc. You can check our performance now at https://www.impactguru.com
The issue we are facing now is that on first open of any page, our website page is taking 3-4 minutes to load, but after the first page loads, all the rest of the pages open quickly for that session. The website page would not take longer than 30 seconds normally. This kind of behavior, is resulting in huge bounce rate and affecting our SEO as well. We need it resolved within the next 3-4 hours from the time of this posting.
Need you to be an expert in Apache server, AWS server, to diagnose, root cause, and to resolve this within 3-4 hours.
