Did the same data spike happen on the 1st day of October, or August?

520MB is less a 1GB, so 677GB 520MB here is just like 677.51GB.

On my side, I do see October 1st has a higher traffic consumption but there was a whole week of a holiday since the 1st, and many staffs had left the office.

so the information might not be useful.

Thank you very much and best regards.
