Blackout(Redirected from Gray Monday)
- Clarion Note redirects here.
Known alternately as Gray Monday, the Blackout saw unknown perpetrators disable some 75-80 percent of the Hyperpulse Generator network in simultaneous attacks and acts of sabotage, effectively crippling interstellar communications.
On Sunday, 7 August 3132 many HPG stations in the Inner Sphere, the Clan Occupation Zones and the Periphery were taken down by what appeared to be some sort of system-virus which caused the HPG core to overload and burn itself out with little collateral damage. A few HPG stations didn't burn out but suffered different, sometimes bizarre failures which also discount a virus being the cause.
A number of stations (at one point referred to as "more modern ones") appeared to be immune to whatever affected the rest, but most of these were taken out in a combination of internal attacks of sabotage and swift and efficient military strikes concurrently with the burnout of the others. With the saboteurs either escaping or dying before interrogation, and the surprise of the military assaults, nobody was able to prevent the attacks or learn who was behind the Blackout. The sole piece of identifying information was a strange insignia worn by some of the attackers: a snake coiled around a sword and set against a blood-red disk.
As a result of the Blackout, interstellar communication by and large collapsed, and was reduced to relaying messages via JumpShip in "pony express"-style. The communications blackout had widespread and far reaching ramifications, plunging the Inner Sphere into chaos. Civil unrest grew when it became apparent that the Blackout would not be quick or easy to fix.
Despite the considerable differences between Clan and ComStar HPG protocols and years spent by ComStar's programmers trawling through centuries of kludged-together code updates and patches nothing was found, and even newly manufactured cores showed the exact same symptoms before burning out themselves. ComStar, whose primary reason for existence was the operation and maintenance of the HPG network, threw everything at the problem, but save for restoring the HPG on Wyatt in 3135, and Millungera in 3137, temporary in the last case, nothing has worked, threatening the organization with irrelevancy, bankruptcy and total collapse.
Tucker Harwell discovered references to a "Clarion Note" emergency protocol, which was consiered by the Word of Blake to be a weapon of mass destruction that would somehow use a Super-HPG to disrupt interstellar communication.
It has been speculated that the appellation "Gray Monday" for a date that is actually a Sunday comes from the fact that the full impact of the event was not felt until the following day (Monday, 8 August 3132).
Only a handful of HPG stations throughout the Inner Sphere survived. The HPG's ability to send messages to places up to 50 light years away considerably boosted the strategic importance of the worlds with functional HPGs (a working HPG is required to send messages, but not to receive them as HPGs effectively "jump" radio waves which can be received with regular radio equipment). Known worlds with working HPGs after the Blackout include:
- Achernar 
- Devil's Rock
- Gacrux 
- Genoa 
- Hsien 
- Imbros III 
- Irian 
- Kessel 
- Menkar 
- Millungera (temporarily; HPG fix did not last)
- New Aragon 
- Northwind 
- Palmyra (destroyed or irreparably damaged during the Battle of Palmyra)
- Terra 
- Thorin 
- Towne (uncertain due to conflicting information)
- Tsamma (possibly; noted as an 'AFFS hub')
- In the BattleCorps PDF edition of the novel A Bonfire of Worlds, the date of Gray Monday is given as 1 August (instead of 7 August) which, being a Monday, may originally have been the correct date. However, according to the Line Developer, the date is corrected to 7 August in a proof of the novel which is in line with virtually all other Dark Age era publications (save one novel by Blaine Pardoe).
