WP Engine will be conducting an emergency security maintenance tonight that will impact your sites. We want to provide as much information as we can, however as is common with security issues such as this, the details of this security advisory are currently under embargo.
In order to implement the patch, WP Engine will be rebooting impacted servers. This emergency maintenance is expected to take place on your site during a window tonight Friday October 21st starting at 10:30PM Central until Midnight.
We believe that the maintenance may result in up to a 10 minute interruption of service to your site during this server reboot. Outside of the downtime, there should be no impact to your site. We will be monitoring the situation closely and communicating with the infrastructure provider regularly to ensure minimal disruption to your site.
We apologize for any inconvenience this may cause.
At WP Engine we take the security of your site seriously. Thank you for the opportunity to support your business.
