We will be applying urgent security updates tonight in conjunction with our hosting company Rackspace. This is planned for 9pm and will result in all Best Companies websites and apps (including mobile) being unavailable for a short time.
I anticipate this being completed within a 10 minute window. This will be completed as quickly as possible.
For those of you that would like a look at the technical reason of the security update:
Potential hypervisor vulnerability (Xen Security Advisory 133: http://xenbits.xen.org/xsa/advisory-133.html)
Update complete, all should be back to normal.
