How to Prevent a Website Crash From Traffic Spikes

Why Sites Crash: The 5 Root Causes

Five root causes, in order of frequency: CPU saturation (uncached PHP executing per visit), entry-process limits (concurrent connections capped), database overload (uncached queries), bandwidth exhaustion, and memory exhaustion.

The response ladder:

1. Stabilize — enable maintenance mode or a static page to stop the bleeding
2. Cache — page-cache plugin + server cache absorbs repeat visits
3. Scale — upgrade the tier or add a CDN in front
4. Find the query — slow-query log; one bad plugin loop can sink a server
5. Prepare next time — load-test before the campaign, not during

Festive-sale spikes are schedulable: pre-warm caches, stage inventory, and move to cloud hosting tiers that breathe. The crash playbook above walks the recovery, and LiteSpeed hosting raises the ceiling itself.

The Caching Layers: Plugin → Server → CDN

Put a cache in front of pages that do not change per visitor, and keep cart, checkout and account pages uncached. After a DNS or cache change, test in a private window so your own browser cache does not lie. Lower the DNS TTL a day before a move, then raise it once the new target is confirmed.

Hosting Tiers by Traffic Level

Two practical notes on caching layers (page, object, CDN): it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.
