On Thursday, many developers experienced problems when they tried to log in to Microsoft's Visual Studio Online service. The IDE experienced several hours of downtime beginning around 9:30 a.m. ET.
Microsoft officials said the problem was not related to the Azure cloud computing service but instead stemmed from bugs in the Visual Studio code. In the early afternoon, Microsoft blogged, "Initial investigation is indicating a contention in our core database seems to be causing blocking and performance issues." At 3:40 p.m. ET, the company added, "We have applied additional mitigation steps. Now the service performance has started to come back to normal. We'll continue to monitor the service and resolve the issue fully."
