Google Calendar is down
One of the reasons I use FastMail (<a href="https://fastmail.com" rel="nofollow">https://fastmail.com</a>) for email and calendar rather than Google is that when outages happen, the explain what is going on (<a href="http://www.fastmailstatus.com" rel="nofollow">http://www.fastmailstatus.com</a>). Outages are inevitable, so having (a) information and (b) the ability to contact a human are valuable features IMO.
