Identified
As a result of the earlier outage at Amazon Web Services, a large number of currency symbols are temporarily showing as unavailable in our API. We believe this is related to a cache failover event that occurred as a result of the AWS incident. We are working to restore full service and will post further updates to our status page as soon as we have any updates.

Identified
We are working hard to resolve this connectivity issue, which we believe was caused by a power failure reported by Amazon Web Services in their us-east region. We will continue to update our status page as often as possible to keep you informed on our progress.
