==================
Service bulletins
==================

Service bulletins are issued for serious security, performance, or
reliability issues caused by problems in SD-WAN software, host
operating systems, or other systems, that cannot be solved except with
manual intervention from partners. Service bulletins are not issued for
problems that can be solved with a normal `software upgrade
<../nodes/upgrading-and-replacing-a-node/upgrading-a-node.html>`__ on a node.
