DNS resolution failure since 2018-04-03 00:00


#1

Since 00:00 this morning (UTC time), it appears that we are experiencing dns resolution failure on two of our load-balanced subdomains. The whole domain is managed by cloudflare, and the load-balancer is only used for georouting to domains which points to aws servers.

Il was working perfectly yesterday, and we didn’t make any changes since.

When enabling cloudflare proxifying on the traffic tab it returns to normal service, but it should -and did- work effectively without it.

The only other information we have is a sudden increase of DNS traffic at that same time:

Thank you for your help.

I’d recommend opening a ticket with support(at)cloudflare(dot)com to investigate.
