We have a 10Mbps (synchronous) connection with our ISP. Recently we have discovered that if a single user is watching Netflix, or if I run Windows Update on a PC, we will totally saturate that 10Mbps and the rest of the users in the company (~200 at this location) suffer very poor internet speed.
Our current firewalls are Fortigates but we're in the process of migrating to Watchguard. That being said, we haven't noticed this being an issue except for in the last few weeks, but we can't imagine what would have changed, and if we run the same sort of traffic through the Watchguard, the same issue crops up (we thought maybe the aging Fortigate was to blame).
Is this something that we should be talking to the ISP about? Is this something we should be controlling with our firewalls?
