Your hostess is not feeling too hot (it's been a rather rough winter) so my usual wordiness has gone wanly MIA, with apologies if you actually read me for my wordiness.
I've been kind of outed by one of my friends (*cough darkoshi*) for discussing this under access lock, so since I'm rather alarmed by one aspect of it I was going to make a public-facing post to discuss it more thoroughly, anyhow. I just didn't know when, but as I like to own what I've been quoted as saying, I guess that'll be right about now.
What Anyone Knows
There are zero confirmed reports that anything's changed for LiveJournal. There are many unconfirmed reports, IP tests and pings done to find on a per-user basis that LiveJournal moved its servers (which store content such as user's journal entries, comments written and received, pictures, Scrapbooks, usericons, mood icons, profile information, friends lists and payment information) from San Francisco, California over to servers located within Russia.
Here's a MetaFilter written by our own brainwane, with enlightening comments made by many people:

I don't want to create public editorial on what it means because I left LiveJournal six years ago over clickjacking done by SUP, the Russian company that runs LiveJournal to this day, and I didn't do so with the expectation I'd ever look back and feel I have to make public comments on any fresh fiascos from here. I really do wash my hands of the place.
Other people have made excellent editorial on it, though. Some links:

What Concerns Me, Part I
The least important thing is many people seem to think if they hit "delete" then poof! LiveJournal can never touch, change, disseminate, share, prosecute them for, or republish any of their stuff again. But LJ still has their stuff; hitting "delete" doesn't change that.
You know how Windows has a thing where you can go into the Recycle Bin when you hit "delete" on files you forgot you needed and just point your mouse at them and hit "restore"? It's pretty neat, isn't it? Lifesaver, sometimes. Same idea.
Nothing changes, you just can't see your LJ anymore, but it's sitting around in a "to be purged" file somewhere on LJ's servers - unpurged and restorable with just a click or two. So don't think deleting it protects your copyright or ensures your freedom from any possible Russian prosecution.
Deleting, as others have said, might make a nice political statement, or make it just a bit harder on LJ staff as they might have to dig around a bit in a server version of a Recycle Bin to find what they want, but that's about it.
What's most important is what you post to LJ from now on. It's basically too late for anything you've already put there.
What you post from Dec. 23rd on (yes, flex with me back in time to the actual date the server move occurred!) is now sitting on servers operating under Russian law, so from Dec. 23rd on, their law applies, not ours (US/stateside here). Act accordingly, as again, I have little desire to make additional comments.
What Concerns Me (the most), Part II
According to scattered user reports like this one and my own at-home tests, at the same time the server change was made the https:// URL protocol was suddenly no longer live nor allowed to function on any part of LiveJournal (and as of this writing, the HTTPS Everywhere add-on won't help, so if that's the only reason you're tempted to install it...*shakes head*...don't bother).
Lack of secure socket technology (in simple language, "sudden lack of a private web connection to LJ") means hackers, spies, governments, and yes, even your nosy next-door neighbor can easily spy on you while you're on LJ.
As almost any LJ/DW user already knows, the implications of that last paragraph are fairly terrifying, as friends locks (LJ) and access locks (DW) are important to nearly all of us, so this change should scare everyone and convince people to stop using LJ until it's corrected, if indeed it ever is.
Because Dreamwidth is a place that's always encouraged people to continue using LiveJournal (DW supports both full imports of all LJs and crossposting to LJ and Wordpress.com) I'll add a disclaimer that by reporting on the LJ server switch and by talking about the current lack of secure browsing on LJ I'm in no way suggesting, "Stop using LJ and forever and ever!!!111!".
In referring to LJ's lack of secure browsing, I *am* simply suggesting you stop using LJ until that gets fixed, but ultimately, what works - and feels - best for you is always your own decision to make.
As far as making comments here goes, I welcome them, but really don't want to talk about Russia. I do enough of that under lock, so if you're on my subscribe list I can consider adding access so you can share all of my sheer, overwhelming joy on that. There is so much joy. But I'm always keen to answer any question(s) you might have on "how to Dreamwidth" or to point you in the right direction if I can't (or shouldn't try to) answer myself.
