Google App Engine is experiencing issues today, causing problems with various services across the web. There have been numerous reports of various outages.
Business Insider mentions Instagram, SlideShare, Sina Weibo, and Orkut. There have also been reports of Dropbox and Tumblr having issues, indicating that the problem may be even larger.
Google has posted a series of updates about the issue in Google Groups:
11:28 AM: App Engine is currently experiencing serving issues. The team is actively working on restoring the service to full strength. Please follow this thread for updates.
12:33 PM: At approximately 7:30am Pacific time this morning, Google began experiencing slow performance and dropped connections from one of the components of App Engine. The symptoms that service users would experience include slow response and an inability to connect to services. We currently show that a majority of App Engine users and services are affected. Google engineering teams are investigating a number of options for restoring service as quickly as possible, and we will provide another update as information changes, or within 60 minutes.
1:51 PM: We are continuing work to correct the ongoing issues with App Engine. Operation has been restored for some services, while others continue to see slow response times and elevated error rates. The malfunction appears to be limited to a single component which routes requests from users to the application instance they are using, and does not affect the application instances themselves.
We’ll post another status update as more information becomes available, and/or no later than one hour from now.
