>This has started again, after several weeks, recently. I have been investigating on the issue. It seems we have the same situation as when it happened before. I blocked several routes but I cannot block them all. This is getting very irritating. I will have to see more into this issue in the next following days.

I was thinking it's a similar behavior as it was before, but luckily now either you isolate it quickly or you found some other way, but it doesn't last more than 5 -10 minutes.
