A disadvantage of cloud computing services is that access to data is dependent upon the reliability of the service provider.
Because I am using a Google Apps account, I was able to temporarily modify the domain name mail servers to a custom IMAP server on the web host while the Gmail issue was resolved. No such protection is available for users of standard webmail accounts.
