Cloudflare blocks an all-time high amount of distributed denial-of-service (DDoS) attacks, with an amount that exceeds 71 million requests per second. DDoS is an attack on a desired server or network where the attacker floods the network with traffic resulting in significant downtime to access the network.

The main area of focus today is the cloud computing platforms which is one of the areas that has been impacted by the attack and how this impacts the space arena. Cloud computing platforms are used highly on the ground for ground station computing. This exist because it takes the workload off the spacecraft itself so that most of the processing is performed, executed and computed on the ground. On top of processing data from the ground, cloud computing platforms for space systems also assists in data management and analytics.
An example would be Amazon Web Services (AWS) which allows for cloud based storage for massive data on satellite systems and computing data. However, if the DDoS strike hit AWS then whoever is using their network for anything not just space purposes would be impacted since the services would be offline. The operators or analysts will be unable to access or process telemetry, mission data, state of health of the spacecrafts, and many more until the network came back up since everything is housed on their networks.

Cloudflare being able to detect the strike and prevent it help prevent a lot of networks from going offline in return saves a lot of money because when networks are down the customers aren’t able to access services especially if they charge of sessions. No network went down during the strike since the previous all time high was beaten by roughly 34%. Imagine the outages and all the lost mission data that couldn’t be processed in time.
