Tell the desk what you need next
We route messages to working instructors. Include enough context to pick the right article links—mention titles such as the blueprint refresh piece or the OSPF adjacency lab if they apply.
Response SLA
We acknowledge inbound mail within one business day Korea Standard Time. Complex routing questions may need two days so the right instructor can read captures.
