... but life is hard, so it broke at one point and I was started wondering on the 5th day that I still see the same news headlines for days now, no news in the IT world ... I was started thinking about selling my stocks 🙂 Then, I found that it's simply not refreshing the feeds.
I was checking the feeds in Internet Explorer (Ctrl + Shift + J -> J, like RSS 🙂 and found that the feeds here were way expired too! Then, started asking around in internal distribution lists. Immediately got an answer from Walter VonKoch, who sent a me a checklist. It turns out that the feeds are updated by a task configured in Windows Task Scheduler. Deleting and recreating the task solved the problem.
