History: Due to the described defense mechanism, SCP-3125's observation history is almost entirely missing. In particular, it is unclear exactly how this containment unit came to be built and how these containment procedures were established.
Much data has been accrued in this containment unit over the course of successive visits by Foundation researchers. This data was brought from the outside in the hope of being useful and left here in accordance with containment procedures. In addition to this database entry, the reader will find multiple electronic copies of the Foundation database, academic data sets of all kinds and extensive public news archives.
As is to be expected, much of this data is not germane to the topic of containing SCP-3125. Nevertheless, correlation and analysis by successive visitors has allowed the following facts to emerge:
1. Although SCP-3125 is not yet fully present in our reality, its indirect effects/foreshocks (for example, SCP-███, SCP-████, SCP-██▓█ and SCP+█████) are easily discovered by any well-equipped memetics research project.
2. Memetics research is, today, a much-diminished science from when it was at its peak. In mid-2008 there existed more than 400 institutions pursuing research likely to uncover SCP-3125, including government agencies, military branches, private corporations, independent laboratories, university research projects and notable amateur groups. Many of these were GOIs or internal divisions within GOIs. None of these groups still exist, except for the Foundation's Antimemetics Division.
3. Almost nobody in the world is consciously aware of this decline, and explanations for the disappearance of these groups have not been forthcoming.
Simple deduction gives that all of these groups eventually discovered SCP-3125 and were consumed by it, and that this is, in fact, the inevitable fate of all competent memetics research.
The Antimemetics Division's persistence is attributed to its specialist training and its ready access to reliable amnestic medication. Despite this, the Division, too, has shrunk considerably in recent years, from a reported staff of well over 4,000 people in 2012 to, as of September 2015, 125. This figure is on track to reach zero before the end of 2015. Over the same period, the Division's physical worldwide presence has similarly shrunk, from a network of Sites and smaller outposts on every continent to this single Site, Site 41. In particular, the Division's headquarters at Site 167 are now missing from the Division's collective memory and presumed neutralized by SCP-3125's concealment response.
Addendum: Further analysis of the available data — specifically, architectural diagrams of Site 41 (attachment 38) — indicates the existence of a second containment unit on Site 41 conforming to the same basic design philosophy as this one. This second unit, S041-B30-000, was built 210 metres below ground level; it features identical broad-spectrum informational cladding but has more than one thousand times the volume of Cognitohazard Containment Unit 3125, along with an amnestic airlock large enough to ingest a Twenty-foot Equivalent Unit shipping container.
Information relating to the date of construction and purpose of S041-B30-000 is absent from Foundation records and is presumed to have been deliberately erased. The unit itself is hermetically sealed, and has been for an indeterminate period of time.Regardless of S041-B30-000's intended purpose, it, like any such containment unit, is capable of acting as a shelter from SCP-3125.
Addendum 2:
And the rest, hopefully, is blindingly obvious.
S041-B30-000 was originally constructed to house a long-term project to construct Hughes' irreality amplifier. While that's been going on, the rest of us have been fighting an unconscious war in order to buy time. We have been losing, but losing as slowly as humanly possible.
The time we have bought is now up. It's an extremely bad sign that nobody inside S041-B30-000 has broken the seal yet, but there is no ground left for us to cede, and there are no more bodies to throw into SCP-3125's maw to slow it down. వ is here, ready or not.
I am going to go to S041-B30-000 and use the machine. I think I can get the information out through the airlock. I think I can get to the vault alive.
This was the plan. It's become garbled in the retelling because of variables, but I know that this was my plan, because I know myself. What else could it have been?
Standard procedure is that I have to tell you what to do next if this doesn't work. That's the asynchronous research covenant.
But I don't have a good picture of who you can even be, reading this and alive. In your scenario there is no machine, Hughes is missing, I'm dead, the Site is ruined, and how'd you even get in here? Can you be Foundation? Are you conscious? Is there a single word of this which you comprehend?
You live in a world bathed with SCP-3125. That's the loss condition.
I can't help someone who doesn't exist.

Addendum 3:
I found your body.
And finding your body was a powerfully disorienting sensation for me, I don't mind admitting. I used to know a Marion. During the brief period in which I knew her, she wasn't one to admit defeat as easily as you. Still, that was a long time ago...
Far be it from me to tell you your business, but I fear you missed a trick. From the evidence I can see, this was never the only "Antimemetics Division" Site. There were others. I imagine they're now all effectively invisible to (most) passers-by, of course, just like this one, but I presume that they, just like this one, still physically exist. Your plan, I think, was in place for longer than you know. And since you weren't at liberty to retain its details, you put it into action more than once.
There is another vault fitting the description, truck-sized amnestic airlock and all. S167-001-6183.
Site 167 is a non-entity, of course, which is most likely why you missed it. It's likely ruined, and it's quite definitely a long God-damned way from here on foot. But still! I think it's better than half a chance.
I could die on this boondoggle too, naturally, as the world has become something of a horror show of late. In any case, I trust that anybody following in my footsteps and reading these additional words will have the presence of mind to pursue the same basic strategy.
Still existing despite everything,
