As of 2:33pm pacific time, our colo is down. This affects both the card.io api and the website. We're working to get more information and to bring all services back online. We'll update this blog post as we know more. Stay tuned!
As of 2:56pm, the card.io api and website are working normally. Our colo suffered a loss of network connectivity, but our machines were never down.
Update: 4:12pm. We've spoken to our colo, and they were under a DOS attack. All card.io systems remain working normally, but we're monitoring closely and will let you know if anything changes.
