There are some changes in the site policy - forbidden loading of files via links in the code of other sites.
These changes are caused by a recent several overload of the server and the identification of multiple doorways sites, using images from the this server, thereby causing significant nontarget server load.
In connection with selection of optimum policy of server request processing of files loading, during last days the failures in loading of the images in the FLASH-application(measurement tool) could be observed! It is connected to different behaviour of various browsers.
Since the policy of a site is based on maximal cross-platform principles, it was obvious that some concessions to anonymity is necessary.
