Hi all --If you have been monitoring our status blog [1] or been to Twitter.com today you have noticed that we are once again experiencing problems due to external causes. The issues causing the downtime require that we once again take measures to bring the site back online.
The first step our operations team must take will likely cause API downtime, especially affecting OAuth. We apologize for the inconvenience and we will work quickly to reduce the impact to the API. We appreciate your patience and I will update you as soon as we know more. Thanks, Doug
