Hi,

Columns for country data in EventLogging tables sometimes not only
contain the country code, but also larger chunks of the client
cookies, which may put sensitive data into the tables.

The corresponding bug is

schemas for end of April 2014 onwards are affected.

If you publish reports exposing the country information/aggregates,
please make sure to validate the country data against exposing
sensitive information, or remove the exposing reports until the issue
is fixed.

Sorry for the inconveniences,
Christian
