SysLogHandlerresolves the address in the constructor, so creating a handler fails if the address is temporarily unresolvable, for example if DNS is not available yet.Only the resolution failure is ignored, and the address is resolved again when a record is emitted.
TimeoutErrorandConnectionRefusedErrorare still raised from the constructor, so the behaviour added in gh-126400 is not affected.🤖 Generated with Claude Code
