Hi Banpot;
We did see utilization return to normal shortly before your email. We did have QOS changes applied and they appeared to be helping traffic management, so that is something you will need to confirm.
Regardless, if this is a business need perhaps this transfer can be scheduled during off hours. Depending on the transfer rates needed, it may be a situation where we will need additional bandwidth as well. Let us know and we can assist with any changes…
