We have implemented monitoring functions in Yandex.Metrica to notify Yandex Advertising Network partners about potential problems accessing ad platforms.
Our monitoring algorithm constantly tracks site traffic statistics and, in the event of sharp fluctuations, checks the availability of potentially problematic sites by requesting their homepage. Partners who sign up for our monitoring notifications receive two types of messages that contain site addresses:
problems with a site if the site does not respond to tests;
regarding site restoration (i.e. when it comes back online).
to fully utilize the site monitoring function, there must be sufficient traffic (more than 100 page views per week): monitoring of sites with low traffic is not guaranteed;
site availability is tested by a robot whose useragent is Mozilla/5.0 (compatible; YandexMetrika/2.0; +http://yandex.com/bots). In some cases, server settings could ban requests from unknown browsers, which could lead to false triggering of site unavailability notifications.
