Main Facility
Item #: SCP-4550
Object Class: Keter
Special Containment Procedures: Personnel working with SCP-4550 are specialised cognitohazard containment teams, each headed by Level 4 personnel. Said containment teams are required to take part in a re-evaluation course every six months.
Electronic equipment/communication devices are not permitted within 50 metres of SCP-4550's outer containment zone outside of controlled exploration. The remains of personnel presumed MIA/KIA are not to be retrieved, even if the above procedures are followed. Any electronic device believed to be carrying SCP-4550's effects is to be immediately incinerated or otherwise destroyed.
MTF Eta-10 ("See No Evil") are to maintain one primary and three backup emergency telegram communication lines, connected to the outer containment zone.
Since initial discovery, all exploration and extraction of SCP-4550-A is to be performed by remotely controlled drones.
Description: Currently, the accepted understanding of SCP-4550-2 indicates that it is a type of electronic cognitohazard or memetic phenomenon. SCP-4550-2 is capable of propagating through electronic equipment, and is presumed to trigger immediately when visually observed1.
SCP-4550-1 is an unregistered but fully operational Foundation Site located close to [REDACTED], USA, which either houses or is the source of SCP-4550-2. No records or witness accounts of this Site have been found. However, security codes from Foundation personnel are able to unlock doors and the Foundation seal is present on the structures, systems and materials within the facility. Whether SCP-4550-2 is directly connected to SCP-4550-1 itself or an infohazardous object inside is unknown.
Any person, regardless of prior Foundation employment, exposed to SCP-4550-2 becomes convinced that they are employed at SCP-4550-1 and will presumably lose memory of their prior life. Moreover, those exposed (designated hereafter as SCP-4550-A) will treat SCP-4550-1 as the only legitimate Foundation Site and assume that other Foundation establishments are faux. So far, all attempts at communication have been met with hostility.
84% of captured SCP-4550-A were in possession of Foundation IDs that were tested and confirmed to be authentic2. Research into the personnel archive of global Foundation personnel records indicate the possibility that SCP-4550 somehow tampers with records as well as memories.
SCP-4550 received its classification following a hostile dialogue between the Foundation Intelligence Department and the Global Occult Coalition; the GOC had lost an intelligence team to SCP-4550 and summarily interpreted it as a hostile action on the Foundation's part. Shortly afterwards, SCP-4550 received its classification.
The absence of SCP-4550-1 (marked Site-█ on recovered IDs) in digital archives suggest anomalous tampering, as records are spread around globally and fractured in the case of foul play. Investigation by Rho-9 ("Technical Support") and Foundation archivists uncovered that information about the former Site-█ is present in outdated paper records. According to said archives, Site-█ was decommissioned and demolished in 1958 after an outbreak of multiple SCPs destroyed the majority of the structure. No information prior to and after this incident has been recovered.
Addendum A
Exploration
Performed exploration, while resulting in loss of personnel, provides additional insight in the spread of SCP-4550-2
Addendum B
Blackbox data
Update: While the raid on SCP-4550 has resulted in the loss of the entirety of the raid squadron, an encrypted signal was broadcast from the personal blackbox of agent ███████5
Addendum C
Termination
The feasibility of termination or otherwise neutralising SCP-4550 is currently under investigation. Multiple proposals are currently heavily debated.
