Webtatic-5 repository EOL schedule
Due to scheduling the EOL of PHP 5.3 on the Webtatic repository, the original Webtatic-5 repository (http://repo.webtatic.com/yum/centos/5/) will become EOL at the same time, 14th September, due to no more packages being maintained on it.
When this happens, the latest RPMs for the repository will be moved to the Webtatic archive server, and not be available as a Yum repository.
Note this doesn't affect the Webtatic EL5 repository, which was created several years later, and supplies several actively updated packages, such as PHP 5.4/5.5, MySQL 5.1/5.5.
