Abstract: Disclosed herein are system, method, and computer program product embodiments for automatically failing over all services operating on a primary region to a secondary region upon detection or notification of a fault in the primary region. When a fault exists on the primary region, the method traverses each cluster containing services operating on the primary region and prepares an input file including a list of service names identifying each service operating on the primary region. Referencing the input file, the method fails over each service from the primary region to the secondary region by modifying a service weight corresponding to each service. This failover process of services may be done simultaneously with failing over any databases corresponding to the failed-over services from the primary region to the secondary region. The method may also introduce a sleep time after modifying each service weight to avoid any potential throttling issues.

Abstract: Described is a method for processing image data to determine if a portion of the image data is affected due to sunlight. In some implementations, image data is sent to an image data store and camera parameters are sent to a radiance detection service. The radiance detection service, upon receiving the camera parameters, retrieves the image data, converts the image data to gray-scale and processes the image data based on the camera parameters to determine a radiance value for the camera. The radiance value may be compared to a baseline radiance value to determine if sunlight is represented in the image data. In some implementations, a baseline model may be developed for the camera and used to cancel out any pixels of the image data that are overexposed under normal or baseline conditions. Likewise, a foreground model may be generated to detect any objects in the image data for which corresponding pixel values should not be considered for determining if sunlight is represented in the image data.

Abstract: Server systems are provided that receive content request and respond with hardware-independent graphics commands instead of, or in addition to, unprocessed content items. Some server systems may act as intermediaries between user devices and content sources. The server systems can obtain content pages from content sources, process the content pages (e.g., using a headless browser), and provide hardware-independent graphics commands (e.g., vector graphics commands, that do not require specialized graphics hardware for execution) to user devices in response to requests for content. The hardware-independent graphics commands can be executed by client browsers to generate a representation of the content page that is the same or substantially the same as the representation that would have been generated by processing the content pages locally.

Abstract: Features are disclosed for selecting preferred content request modes on a client computing device when initiating content requests. The request modes may correspond to direct requests (e.g., requests made from a client device directly to a content sever hosting requested content) or to indirect requests (e.g., requests made from the client device to the content server via an intermediary system). The preferred request modes made be based on a statistical analysis of performance data (e.g., prior content load times) observed or recorded by the client computing device in connection with prior content requests. Randomly selected request modes may be used to provide additional data for performance analysis.

Abstract: Technology for a publish-subscribe messaging method may include determining a schema for structuring raw data published in a publication by a publisher in a publish-subscribe system at a channel node in a network and distributing the schema from the channel node to other channel nodes in the network. The method may include identifying the publication from the publisher at one of the channel nodes and applying the schema to the raw data of the publication at the channel node, transforming the raw data to transformed data. The transformed data may be provided at a subscriber in the publish-subscribe system.

Abstract: An intermediary system operates as an intermediary between content servers and user devices, and provides services for determining page authority based on user browsing behavior. One such service involves receiving user browsing behavior from at least one browser on a user device and using the browsing behavior to assign an authority ranking to a content page (e.g., web page). The intermediary system can determine the content page authority based on explicit user authority rankings and/or implicit authority indications in page traffic data.

Abstract: Network accessible content, including but not limited to web pages, can be analyzed to identify characteristics of the content. Historical content requests associated with users and/or other user-specific information can be analyzed to identify user interests. Content can then be provided or recommended to users based on content characteristics and user interests. The content that is provided or recommended may be trending content that has at least a threshold level of popularity, became popular recently, and/or is associated with a threshold level of social network activity.

Abstract: Features are disclosed for providing a browsing experience for users where the browser interface and/or page layout are modified based on aggregated user preference data. Various browser modules can be exposed for a given content page based on analyzing data representing interactions of users with browser modules while viewing the content page. Accordingly, the modules exposed to users viewing the page can include useful functionalities for interacting with the content. Content page layouts can also be dynamically modified based on analyzed interactions of users with elements of the content page.

Abstract: Server systems are disclosed that receive content requests and respond with hardware-independent graphics commands instead of, or in addition to, unprocessed content items. The server systems can also generate text information regarding text in the requested content items, and provide the text information to user devices so that the user devices can have knowledge of the text in the content item. The user device can use the text information to handle user interactions with the content item, including copy, paste and search commands and other similar commands. Accordingly, the hardware-independent graphics commands-based representation may provide text interactivity and effects not otherwise available to content representations based on graphics commands or images of content.

Abstract: Features are disclosed for generating request decision models for use by client computing devices to determine request paths or modes for content requests. The request modes may correspond to direct requests (e.g., requests made from a client device directly to a content server hosting requested content) or to indirect requests (e.g., requests made from the client device to the content server via an intermediary system). The request decision models may be trained by a machine learning algorithm using performance data (e.g., prior content load times), contextual information (e.g., state information associated with devices at times content requests are executed), and the like.

For example, a web content magazine can be generated by obtaining a user-specific interest model for a particular user, determining a reading time period, obtain web content that can be read by the user within the reading time period, processing the obtained web content to generate a web content magazine, and providing the web content magazine for display. The web content magazine can contain an amount of content that can be read by the user within the reading time period according to the user's reading speed.

Abstract: An intermediary system operates as an intermediary between content servers and user devices, and provides services for improving page load times as seen by end users. One such service involves converting a retrieved content page (e.g., web page) into a number of encoded layers that can be decoded and rendered by the user device. The intermediary system determines a suitable encoding technique for each of the layers. The intermediary system sends the encoded layers to a browser component running on the user device for rendering by the GPU.
