This is what you called a garbled file, one where a run of binary zeroes
has been put somewhere where it doesn't belong. Probably a PUT8806 RSCS,
but we've not been able to locate it. FRULM11 is not affected, US sites
are not affected, but all sites past FRULM11 are affected (sometimes).
The interesting news is that neither FRULM11 nor its adjacent node,
FRORS12, touched their RSCS recently.
