ziplinks are used, SVINFO is the first compressed message.
The burst consists of SID and SERVER messages for all known servers, UID or

BAN
charybdis TS6
capab: BAN
source: any
propagation: broadcast (restricted)
parameters: type, user mask, host mask, creation TS, duration, lifetime, oper, reason
Propagates a network wide ban.
The type is K for K:lines; other types are reserved.
The creation TS indicates when this ban was last modified. An incoming ban MUST
be ignored and not propagated if the creation TS is older than the creation TS
of the current ban. If the ban is identical, it SHOULD NOT be propagated to
avoid unnecessary network traffic. (Two changes to bans that set the TS to the
same value may cause desynchronization.)
The duration is 0 for an unban and relative to the creation TS for a ban.
When the duration has passed, the ban is no longer active but it may still
be necessary to remember it.
The lifetime is relative to the creation TS and indicates for how long this
ban needs to be remembered and propagated. This MUST be at least the duration.
Initially, it is usually set the same as the duration but when the ban is
modified later, it SHOULD be set such that the modified ban is remembered at
least as long as the original ban. This ensures that the original ban does not
revive via split servers. This requirement is only a SHOULD to allow for
implementations that only inject bans and do not remember any; implementations
that remember and propagate bans MUST set the lifetime appropriately.
The oper field indicates the oper that originally set the ban. If this message
is the initial propagation of a change, it SHOULD be sent as * (an asterisk).
The reason field indicates the reason for the ban. Any part after a | (vertical
bar) MUST NOT be shown to normal users. The rest of the field and the creation
TS and duration MAY be shown to normal users.
