Hi, KnownHost here.
We’re attempting to reach out via ticket #2151006 and/or directly to the CF NOC regarding this issue. We began receiving reports of this issue intermittently last night which aligned to the times CF was conducting DC maintenance.
We monitor our network & all routes internally and externally from multiple points across the globe and have recorded zero instances of network instability during this period. CloudFlare does not seem to provide any looking glass to test these network routes from their different locations and points of presence.
We will continue to attempt to work with CloudFlare to identify these issues, but only CF will be able to provide the information necessary to troubleshoot this further from a network perspective.
