Been there, done that with VPS crashing from traffic spikes. Lesson learned — don’t cheap out on RAM or CPU cores. I usually go for at least 4GB RAM and 2–4 dedicated CPU cores, depending on the site. Storage type matters too  SSDs make a huge difference. I switched to vikhost.com after some headaches elsewhere, and their VPS setups have been rock solid, even with sudden traffic bursts. Their support is quick too, which helps when you’re stressing out!
