The Iraq War Logs site run by WikiLeaks has been showing some choppy performance since last weekend, when its remaining Amazon EC2 instance stopped responding to HTTP requests.
Over the past week, the DNS configuration for warlogs.wikileaks.org had been directing traffic to two IP addresses on a round robin basis. One of these IP addresses was at Octopuce in France, and successfully handled half of the HTTP requests sent to http://warlogs.wikileaks.org; however, the remaining 50% were directed towards an Amazon EC2 IP address in Ireland, which stopped accepting connections to port 80 last weekend.
WikiLeaks appeared to fix the DNS problem today (Friday) – warlogs.wikileaks.org is now being served from just a single IP address in France. This is in contrast to the situation a few weeks earlier, when the site was being served from as many as 5 IP addresses, presumably to make the site more resilient to attack and high demand.
