10:15 We are aware of ongoing performance issues affecting the opencorporates.com website.
Please bear with us while we investigate.
12:10 We have identified the cause of the problem to be a problem caused by misconfiguration of our DNS services in advance of our planned maintenance.
This was causing an outage for many visitors, with only 1 out of 3 DNS servers providing the correct IP addresses.
The problem has been worked around temporarily, with a full fix to follow.
We apologize for the interruption to service and thank you for your patience.
