Slow network detection and response

A non-transitory computer-readable storage medium storing processor-executable computer program instructions that, when executed, cause a computer processor to perform a method, the method comprising:

• receiving a first notification, from an exchange by a control system, of a first opportunity to provide supplemental content to a browser;
• responding, by the control system, to the first notification by sending a first response pointing to instructions that, executed by the browser, cause the browser to request and retrieve:
• from the control system, an initial impression content;
• from a supplemental content server, a first supplemental content;
• and
• from a tracking server, a tracking content;
• wherein the supplemental content server and the tracking server are on a different domain than the control system and wherein the supplemental content server and the tracking server are on different domains;
• receiving, by the control system from the browser, the request for the initial impression content at a first time;
• not receiving a first indication, before the end of a first predetermined period of time after the first time, from the exchange by the control system from the tracking server, that the tracking content was requested by the browser;
• and
• at a second time, after the end of the first predetermined period of time after the first time, receiving, by the control system, a second notification of a second opportunity to provide supplemental content to the browser;
• and
• responding, by the control system, to the second notification by sending a second response pointing to instructions that, executed by the browser, cause the browser to request and retrieve from the supplemental content server, a second supplemental content, wherein the second supplemental content requires less networking capabilities to retrieve than the first supplemental content.
