IfWindowsUpdate is still not working properly, and Microsoft recommends that users contact their ISP
Windows Update users will not be able to serve in the near future due to the impact of network infrastructure incidents caused by the global disruption of external DNS service providers. Due to one of the external DNS vendorsThe serverEnd-to-end updates cause DNS record corruption, affect Windows Update update distribution services, and affect access connections. DNS records resumed at 00:10 UTC time on January 30, 2019, but the downstream effects continued. We have observed that this problem has been fully alleviated, that most local Internet service providers (ISPs) have updated their DNS servers and that Windows Update services have been restored. If you still encounter download failure, please contact your local ISP provider.
Although this is not the caseMicrosoftService issues, but we will take any disruption of customer service seriously. We will work with partners to better understand this so that we can provide better quality services in the future, regardless of the complexity and diversity of global network providers.
