As italian with a direct experience both times with it, I think Tiscali is an order of magnitude better now than when it was a unicorn, maybe these investements require profits so that companies need to cut on quality?
I wasn't aware of that, I was speaking as a user, maybe they're having an hard time to re-conquer customer's trust, but right now their connection is quite stable and fast
And BTW, congrats although 20 years late :)!
