Massive cyberattack hits Internet users

(CNN) -- Internet users around the globe are facing slowed-down service, thanks to what's being called the biggest cyberattack in history.
The prolonged denial-of-service assault is targeting The Spamhaus Project, a European spam-fighting group that has gone after CyberBunker, a data-storage company that offers to host any content "except child porn and anything related to terrorism."
The organization has been in a long-running feud with CyberBunker and claims spammers use it as a host from which to spray junk mail across the Web.
Internet security firm CloudFlare said Spamhaus contacted it last week, saying it had been hit with an attack big enough to knock its site offline.
Security experts say the attack uses more sophisticated techniques than most DDoS (distributed denial of service) attacks and targets the Web's infrastructure, which has led to other sites performing slowly.

"It's the biggest attack we've seen," Matthew Prince, CloudFlare's CEO, told CNN.
The FBI is involved in the investigation into the cyberattack on Spamhaus, though a bureau spokesman didn't provide any details on the FBI's role or the scope of the probe.

The Spamhaus Project is a nonprofit organization that patrols the Internet for spammers and publishes a list of Web servers those spammers use. According to Prince, the group may be responsible for up to 80% of all spam that gets blocked. This month, the group added CyberBunker to its blacklist.

Remember the time when we had to use a 56KB Modem? Now we are at 100 GB Per Second... Unbelivable 

World’s fastest wireless network hits 100 gigabits per second, can scale to terabits
German researchers have combined photonics and electronics to create a world-record-breaking wireless network that can send and receive data at a heady 100 gigabits per second (Gbps). This beats the same team’s previous world record of 40Gbps. At 100Gbps, or a transfer rate of 12.5 gigabytes per second — ten times faster than Google Fiber — you could copy a complete Blu-ray disc in a couple of seconds.

To achieve such a massive data rate, researchers from the Karlsruhe Institute of Technology (KIT) used a massive swath of bandwidth at around 240 GHz — close to the terahertz frequency range. To create the signal, two laser beams (carrying the data) are mixed together (using a photon mixer made by NTT Electronics). An electrical signal results, where the frequency of the signal (237.5 GHz in this case) is the difference between the two optical signals. A normal antenna is then used to beam the signal to the receiver, where a fancy chip fabricated out of fast-switching III-V transistors (pictured below) is required to make sense of the super-high-frequency signal.
