No available Fortiguard SDNS servers?

[TecnetRuss]

It looks like another bad day for FortiGuard servers. We're getting a lot of complaints across the board from various customers about mainstream web sites not loading with a blocked category message (including fortiguard.com and forum.fortinet.com!).  The DNS filter and Web filter logs are filled with "web ratings error occurred" and "No available Fortiguard SDNS servers".  This is affecting FortiGates using HTTPS and UDP, port 53 and 8888 under System/FortiGuard.  The only work-around is to enable the "Allow websites when a rating error occurs" on the WCF profile and/or "Allow DNS requests when a rating error occurs" on the DNS filter profile depending on the client's config, but of course this allows access to unwanted websites while FortiGuard is not responding.

It's frustrating that this seems to be a monthly occurrence.  Anyone else seeing this or is this a regional issue (pacific northwest)?

The problem resolved itself for me within a few hours of starting.  For what it's worth I did log a ticket with support and uploaded logs to record the incident.
