Should I stop testing during peak hours?

As an e-commerce manager, I'm constantly trying to optimize my store's performance, but I'm uncertain about the best practices for A/B testing during high-traffic periods like holiday sales or flash events. I want to improve conversion rates and user experience, but I'm worried that running tests during peak hours might disrupt sales or provide misleading data. What are the strategic considerations for continuing or pausing tests during high-traffic periods?
