What are the potential consequences for a website or service targeted by a 3.8 Tbps DDoS attack if Cloudflare isn't in place?

Without DDoS protection like Cloudflare, a website or service would almost certainly experience a complete outage. The sheer volume of traffic would saturate network bandwidth, overwhelm servers, and likely crash critical infrastructure. Recovery would be extremely difficult and time-consuming, leading to significant financial losses, reputational damage, and loss of customer trust.
