How do I prepare my site for the traffic spike during event week? — answered by Engineer Saeed Baatiah
Three measures cover most cases: enable caching and a content delivery network so pages are served from the point nearest the visitor; load-test at roughly three times your expected peak a week beforehand; and monitor response time daily during the event with an automatic alert rather than learning of an outage from a customer complaint. Shared hosting is the first thing to buckle under a sudden spike — if you are on it, move before the event rather than during it.
