Hydra Diplomatic CCTs

Telegram from CANCOMMRON Rockcliffe to CANFORECHED, for DCRS 2-4-3. Telegram notes that Rockcliffe is "the sole DND engineering agency for the subject ccts in the Ottawa area and the connecting facilities between London and Washington." Telegram indicates that recent notifications of circuit down times have been in "less than a service message," possibly compromising the security of the network. Rockcliffe requests in future these notifications be sent in more secure format and request record on down times of all Hydra circuits.
