Blackberry
On October 10, 2011, Blackberry had an outage in Europe, Middle East, and Africa. By October 12, Blackberry internet service went down in North America. Blackberry apparently had an unfortunate issue regarding data overload due to switch failures in their two data centers which was the main problem that had caused their service disruptions.
Playstation Network (PSN)
On april, PSN got hacked by "anonymous", who was known to be part of the 4chan website. Members of 4chan were also responsible for hacking other popular websites and sending DDoS attacks to their servers. The attack on PSN occured between April 17, 2011 and April 19, 2011. During the hacking, 77 million accounts were stolen, making it one of the largest data security breaches in history. Itprevented Playstation 3 and Playstation Portable users from playing online. This forced sony to turn off the PSN on April 20, 2011.
During the Attack, they discovered that the intruders planted a file on one of their Sony Online Entertainment servers named "Anonymous" with the words "We are Legion". Playstation is now using inhanced levels of data protection and encryption; enhanced abilities to detect software intrusions, unauthorized access and unusual activity patterns; additional firewalls, etc.
Sony had not released any information as of how they got hacked, or what they did to stop the intruders, as that even is now an ongoing criminal investigation. The inormation could be used to exploit vunerbilities in systems other thanSony's that have similar architecture to the PSN.
