Is this a WAN or LAN problem?

Hi all,

We've got a client who's been having irregular internet dropouts for a few months now. They've become more common in the last 2 weeks which is why I'm writing this post. At most, they'll happen 4 times a day. They have an AVD environment which makes this even more critical.

The method we know it drops out is when the remote session drops out and the continual ping the onsite IT guy has running to an external address and the gateway. The one to the external address will stop for around 10 seconds but the internal one to the gateway will continue. The gateway is a Watchguard M200. We've got a dimension server setup and we can see the VPN to Azure reastablishing but not a lot else. The WAN provider has assured us that it's not their problem as they've been out and replaced all of their equipment but they haven't been particularly helpful and I'm not confident in their monitoring. What steps would I take next? Is their any free tools I should look at that will help identify where this issue may lie?
