MISO's real-time fuel mix service has been down for several hours. This may be related to a widespread Azure outage: https://azure.status.microsoft/en-us/status. Our data coverage will resume when the service becomes available again. Due to the nature of the source, we will not be able to backfill data that was missed during the downtime. Alternate sources ISO-H and EIA are not affected and will be available for this time period tomorrow.
