Hey @theant, The throughput test verifies bandwidth between the MX and the Meraki cloud; it might not always give you the results you expect as it depends on various factors and on average I would suggest to take at least 3 and average them. Aside from that, another few tests you could try is to connect to a VPN service and check if there is any difference in the performance getting to the affected websites. You could also try and connect directly into the ISP modem and bypass the MX, to confirm whether or not there might be issues with the configuration that might be the cause of the problem; the most common cause is normally some wrong order of traffic shaping rules, but it might not be your case. Let us know how you get on 🙂 Giacomo
