Cisco Umbrella VAs deployment

[gabelz]

Hi all,

i have a doubt regarding migrating Umbrella to new IP directions.

Explanation:

at the moment i have Umbrella deployed with 2 VAs pointing to same site,e.g. SFO and ip addresses 10.1.1.1  and 10.1.1.2 and all is working properly.

My question,i need to deploy two brand new VAs from old ones on-prem to Cloud with 2 different IPs for the new ones;could be possible deploy the new VAs in the cloud pointing to same site SFO in Umbrella and at same time using the old ones as well?Is there a max VAs for site?I know Umbrella VAs need to be deployed in pair,but is 2 the max VAs as well¿?I asked this in order to know if old and new VAs can coexist at same time and work?

Thanks in advance!

Hello Gabelz,

There is no limit to the number of Virtual Appliances you can deploy; you may stand up as many Virtual Appliances for your organization as you see fit.

We also highly recommend that you at least deploy two virtual appliances (VAs) per Umbrella Site. VAs must be deployed in pairs to ensure redundancy at the DNS level and to allow for updates without downtime.

Thank you for the information.  I checked the rules and nothing is blocking the traffic, and I don't see any blocks or denies for this VAs. .  They just randomly stops working.  This is only happening to the VAs sitting in Azure.  I am about to deploy some more, so I can do more testing if it is something with those VAs.  Sometimes, they will lose connection to OpenDNS then start working again on their own.  It is really odd.  We have VA pairs for the sites.  Any logs that I can check?
