Pagely is conducting upgrades to WordPress Core Version 4.9.2 for all hosted sites. For more information about this release, please check out https://wordpress.org/news/2018/01/wordpress-4-9-2-security-and-maintenance-release/
We typically have the vast majority of sites patched within the first 48 hours of any security related update becoming available. If you are one of the few sites not on a 4.9 release yet, you will first receive a patch version for the minor version you are currently on (4.8.4 => 4.8.5, 4.7.8 => 4.7.9, etc.) during the initial rollout. Supplementary passes will get any sites not on 4.9 to the very latest release. If we have problems patching your site, or if you've requested a hold in the past, we'll be in touch!
While these updates are in progress, you may temporarily experience slowdowns or server errors. These are self correcting and normal during the update operation. Cached pages are not affected by any load imposed by the patching.
As always, you can stay up to date on the latest security happenings on our security blog! https://pagely.com/blog/pagely-security-updates/
