Back online after few days on Chinese Mountains I discovered lots of interesting informations about Internet disruptions which occurred earlier this month and impacted more than 90 millions Internet users. Outages were due to up to cuts on up to 9 submarines cables located, for most of them, around the Arabian Peninsula.

"I Love Bonnie" published on the 12th the excellent "The Submarine Cables - A Complete Guide to the 2008 Internet Outage". The post contains tons of informations and links and provides a detailed review of the events. Media coverage can be found on Renesys site. Steven M. Bellovin professor at Columbia University analyzed the possible causes of these outages.
Some also speaks, indeed, about conspiracy

8th of November: World Usability Day "Make life easy"
Swiss UPA, the Swiss chapter of the Usability Professional Association proposes to ease access to free public wireless networks using a specific sign ((o)) that would help users to detect easy to use wireless networks.
Today, before getting online using a wireless device, users have first to find an user-friendly wireless access point and then try to connect to it.
The user has to detect which wireless networks are available from his location and check if they are public and free of charge. Often wireless network names do not inform the visitor if the access to the network is free or not. The wireless access point might not be protected but once connected users are redirected to a page where they will be invited to purchase access rights.
Swiss UPS also highlight the fact that once connected to a free and public wireless network, it is not uncommon to reach an authentication page before getting access to the Internet. This procedure has 2 main disadvantage:
- Some authentication pages cannot be completed when using a Smartphone or a PDA.
- Some services such email, Instant Messaging, VoIP, etc… do not require the use of a browser and users cannot pass easily through this authentication method.
To make users' life easier, Swiss UPS proposes to include at the beginning of the SSID (Service Set Identifier which broadcasts the name of the wireless network) of public and free wireless networks the following distinctive sign: ((0))
Usage of the sign ((o)) is free and open to all individuals, collectivities and organizations which operate a WiFi network respecting Swiss UPA usability charter.
