Ahead of the PCI move to deprecate the use of ‘early TLS’, we’ve previously taken steps to disable TLSv1.0.
Unfortunately at that time we encountered some issues which led us to rollback these changes. This was to allow users of operating systems that did not – yet – support TLSv1.1 or higher to download Percona packages over TLSv1.0.
Since then, we have been tracking our usage statistics for older operating systems that don’t support TLSv1.1 or higher at https://repo.percona.com. We now receive very few legitimate requests for these downloads.
Consequently, we are ending support for TLSv1.0 on all Percona web properties.
While the packages will still be available for download from percona.com, we are unlikely to update them as the OS’s are end-of-life (e.g. RHEL5). Also, in future you will need to download these packages from a client that supports TLSv1.1 or greater.
For example EL5 will not receive an updated version of OpenSSL to support versions greater than TLSv1.1. PCI has called for the deprecation of ‘early TLS’ standards. Therefore you should upgrade any EL5 installations to EL6 or greater as soon as possible. As noted in this support policy update by Red Hat, EL5 stopped receiving support under extended user support (EUS) in March 2015.
To continue to receive updates for your OS and for any Percona products that you use, you need to update to more recent versions of CentOS, Scientific Linux, and RedHat Enterprise Linux.
