We use Outlook.com calendar to share church event information via a Shared Calendar.  About 1-2 weeks ago, this service stopped working for us.  

The calendar is at:  https://cid-bdc4478030dc71de.calendar.live.com/calendar/private/18e9512b-ed24-434d-8948-e430c372fad1/561a15be-a07f-4a65-892d-f5db55632400/index.html  

In addition to posting to the calendar directly by logging into Outlook.com, we formerly were able to use the Outlook Connector to update the calendar from Outlook 2010 from the desktop PCs in our office...we are also seeing trouble with this.

When I use IE 9 or Safari or Chrome to try to view the calendar, I get a error message.  For Safari, it can't find the server, for Chrome: The server at cid-bdc4478030dc71de.calendar.live.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
