Bitcoin-Status is a site that monitors the uptime of the major bitcoin exchanges, wallets, and other services. The site monitors if they are online, if they have had downtime in the last 24 hours, last 60 minutes, or currently. They also provide charting of up & downtime, reaction time, and loading time. The Bitcoin-Status API provides users free access to the data feeds for all of the tracked exchanges and service sites. Users can get the data in XML, JSON, or ARR.
