Quote:Windows Update went down in late January due to what eventually proved to be a DNS issue encountered by several ISPs, with customers in several regions, including the United States and the UK, no longer being able to update their devices.

In February, Microsoft explained that it was working with partners to resolve the problem and instructed users to get in touch with their ISPs to flush their DNS records.

“A software update to the external provider’s DNS servers resulted in the distribution of corrupted DNS records that affected connectivity to the Windows Update service,” Microsoft explained at that point.

In a March 8 update, the company points users to KB4493784, a new knowledge base article that includes information on how to resolve the problem hitting Windows Update.

“If you are still unable to connect to Windows Update services due to this problem, please contact your local ISP or network administrator and refer them to this KB which will help them resolve the DNS issue for you,” Microsoft explains.
