Bit.ly offers alternative domains in connection with the riots in Libya
On Saturday, the Internet in Libya was really turned off. But even a few hours before, the executive director of the Bit.ly service hastened to dispel concerns : Bit.ly's performance is practically not in danger.
In general, for Bit.ly or any other domain in the .ly zone to stop resolving, you need five DNS servers for the .ly zone offline. But unlike Egypt, the situation here is more reliable. Two of the Libyan DNS servers are located in Oregon, one in the Netherlands and two more in Libya.
True, the director of Bit.ly kept silent about who exactly controls the overseas .ly servers. If they are controlled from Libya, then their foreign location means little: one command shutdown -h now is enough.
In addition, the local dictator Gaddafi could theoretically deliberately return incorrect answers to DNS queries to Bit.ly for monetization or political propaganda. Due to these potential risks, the Bit.ly service offers to use spare domains: http://j.mp/ andhttp://bitly.com/ . Any link with bit.ly can be rewritten to j.mp, simply replacing the domain name.
