Question
Warehouse users are reporting performance issues at the end of each month when trying to access cloud applications to complete their end of the month financial reports. They have no problem accessing those applications at the beginning of the month. Network information:

Explanation
The traffic shaper configuration shows the Warehouse VLAN is limited to 75 Mbps, the lowest of any department. At the end of each month, warehouse users run financial reports - a data-intensive task requiring significant bandwidth to cloud applications. The 75 Mbps cap becomes a bottleneck under this peak load, causing the observed performance degradation. This explains why the issue is periodic (end of month) and not constant. A finance department bandwidth limit (A) would affect finance users, not warehouse. A proxy blocking access (B) would result in no access, not slow access. Firewall deny rules (C) would block access entirely, not degrade performance. The traffic shaper bandwidth ceiling on the warehouse VLAN is the clear cause given the evidence.
