Users across globe have reported that statistics like IP Reputation, Domain Reputation, etc. have stopped updating in Google Postmaster Tools since 18 December, 2021.
But don’t get anxious, you should know this has not happened for the first time. This same issue has happened many times before and over the time the glitch gets rectified by Google team. But to get this resolved bit faster, we have reported this issue to Google team directly and hope this time also the data gets populated soon.
Thinking, what senders can do? We suggest all senders to report this problem using Feedback utility in GPT and post on Google Product Forums. This will help Google engineers to prioritise this issue.
