Today's update from ISC indicates that this was collateral damage from
an attack on one of the ccTLD registry operators which they host
secondary auth servers for, and that for now it is mostly mitigated. We
will continue to monitor.

Having successfully stabilized, updated and rationalized OARC
infrastructure over the past year, rest assured that after the past
week's incidents, giving it greater geographic/provider diversity and
higher availability rank high on our next round of development plans...
Thanks for all the offers of help with this.
