tech chat says:

I understand. As I said, Automated process performed by system whenever it found an issue so the reboot will make bigs to clear. I can assure you that it wasn't done by anyone manually from our end or yours. Everything is safe and real sorry for your inconvenience.

Then gets "network team" and says nothing found.

Does anyone else get same?
