Many devices, one target
A crowd can block a shop’s entrance. Likewise, an attacker can direct many devices to flood a website with requests, leaving it slow or unavailable to real visitors.
Traffic from many places can look like normal visits, making it hard to block.
Reducing the impact
Specialist services can filter excess traffic before it reaches the site. Teams also use rate limits, caching, and extra capacity. No measure guarantees protection, and a surge of real visitors may look like an attack. Teams check the cause and keep customers informed.
