I had the same issue, restarting my router fixed the issue.
Edit: Started reading the new Ryzen article and a minute later I refreshed the page and it is back again. An error (403 Forbidden) has occurred in response to this request. Was working for a minute or two only.
This issue was severe last week, but our team was able to get things running again. However, there's still work going on to make sure this issue doesn't return. In the meanwhile, we may still see some issues accessing certain regions or pages while that work is being done. Please bear with us.
