Pantheon, our hosting provider for IndieCommerce 2.0, is reporting infrastructure issues. These issues could cause 2.0 sites to be slow or unresponsive. Most 2.0 sites are up and running, but we have had a few reports of outages. We are in communication with Pantheon as they work to mitigate the issue and will continue to monitor and provide updates here.
