Exchange Online Improvements to Accelerate Replication of Changes to Azure Active Directory
It looks like this has negatively affected the Exchange Online on-boarding migration tool. Every migration batch we try to run (migration type: G Suite) now fails, with the following error for each user in the batch:

It certainly seems however that there are underlying infrastructure issues in Office 365 that are causing this and other issues.
