On Wednesday 9/21 between 2011-09-21 16:32:37 and 2011-09-21 16:36:37 INTERDUBS might have been unreachable for some people.
One of our network providers did some configuration changes that were flawed and resulted in overloaded circuits on their end. They addressed the issue less in four minutes and were responsive and forthcoming with details on this matter. Since we have used them for quiet some time with great success in terms of performance, reliability and service we do not see this as a trigger to replace them in our provider mix.
Sorry should you have been impacted by this.
The actual INTERDUBS system was not impacted by this problem in the surrounding network.
Judging by the traffic volume we see that only a small minority of clients has been impacted.
