Google Analytics - NOT amateur radio

For some weeks the map showing me where the audience for the blog comes from during the day has not been working. This particular map is only available to the blog owner.

In the past sudden increases in visitor numbers always tied up with increased interest from eastern Europe and Russia. These "blips" seemed to happen about once a month. I assumed these were probing bots rather than visits from people with a genuine interest. With the map not working I cannot tell where visits are coming from.

Already today my blog visits are way up. Already I have well exceeded the number of visits on a normal day. Now, these visits could be genuine, but they look exceedingly suspicious to me.
