Microsoft has been having DNS issues, with the result that Windows users did not get their updates. Microsoft has confirmed that the problems are solved and updates can be installed again. 

Windows Update went globally offline, although the issue presented itself mostly towards users from the United States and the United Kingdom. Windows Update no longer wanted to work due to DNS problems, Microsoft said. Microsoft mentions that the issue at hand should have been be solved on the day itself, but that there were still people with connection problems because the DNS servers had not yet been updated with the new data entries.

“The Windows Update service was impacted by a data corruption issue in an external DNS service provider global outage on January 29, 2019. The issue was resolved on the same day and Windows Update is now operating normally, but a few customers have continued to report issues connecting to the Windows Update service. We expect these issues will go away as downstream DNS servers are updated with the corrected Windows Update DNS entries.”
