Several Microsoft services went down amid a US-wide outage affecting tens of thousands of Americans.
The issue appeared to start around 7.50am ET Thursday as many on the East Coast started their work day.
Microsoft said it monitored their systems and 'confirmed that impact has been remediated,' around 11 am ET.
The company attributed the cause of the issue to 'a change within a third-party ISP's managed-environment.' A third-party ISP is an online service provider that is independent from the company that hires it.

By 10 am ET, more than 90,000 users reported Microsoft service outages to Downdetector, a site that tracks online service outages.
But this is probably an underestimate, as not every affected user may have submitted a report.
Microsoft's Azure cloud platform also said that they investigated customer reports of a potential issue connecting Microsoft's services from AT&T networks.
This was Microsoft's second major outage within the last two months.
On July 30, the company suffered a global outage that restricted access to Microsoft 365 services such as Office, Outlook and Azure.
Microsoft has since confirmed that the July outage was triggered by a distributed denial of service cyberattack, which is disrupts the normal traffic of a targeted server, service or network by overwhelming it with a flood of Internet traffic.
