Microsoft dynamic CRM online 2016 service update 2 (8.1.0.0452) was postponed

Hello,

We was supposed to have an update on our instances of CRM online last week, but Microsoft postponed the update.

Did somebody know why the CRM online (8.1.0.0452) update was postponed, and when is supposed to be release?

Our data center is North America

Thanks
