Explanation of today's outages:
The configuration of the rootserver segments that control IP address routing stopped working suddenly leading to a network outage. The root cause of this is still being investigated but the issue was fixed at approximately 11AM EDT. We do apologize for the inconvenience of this occurring and are taking steps to ensure that such a major failure like this does not happen again.
That was after this morning's two-hour outage. Then there was another one from about 2 to 3:30. The explanation on the host's support recording was about the same. Hopefully that was the last one.
