The importer is still running, we swear! It's just very busy.

People who are worried because the import of their LiveJournal account has been running for a long time with no real signs of progress: please don't be concerned! The import queue is currently a little long. (In the same way that Mt Everest is a little tall and the Mariana Trench is a little deep.) We're limited in how many import jobs we can run simultaneously and how quickly we can start the next import after one finishes: LiveJournal, like all sites, has restrictions on how frequently we can programmatically request data from their site, so the import queue can get very backed up at times like this when more imports are being started than are finishing. If you look at the import queue and the numbers don't seem to be changing much, or are only going up, it doesn't mean that no imports are finishing: it means a lot of additional people have scheduled an import since the last time you reloaded.

As long as you haven't gotten a failure message in your on-site inbox, your import is still running. (Even if you have gotten a failure message, your import may still be running: if the site thinks that the failure is something that might correct itself, like being unable to connect to the remote site, it will retry for a few times before giving up.) If you have gotten a failure message, the error message in your inbox should tell you what went wrong.

The three common problems right now: 1) you mistyped your username and/or password; 2) you need to agree to LiveJournal's new ToS before they'll permit you to access the data in your account; 3) an entry or entries in your LiveJournal account have a text encoding mismatch and you need to follow the link in the error message to fix it on LJ.

If you haven't gotten a failure message, your import is still waiting in the queue, and will run when it makes its way up to the top of the queue.

People keep asking us how long the queue is (by which they mean, how much time will it take for a job just started to successfully finish: length of time, not number of jobs waiting). I would love to be able to give you a definite answer! It's really, really hard for us to predict how long it will take for a job to get up to the top of the queue, though: how long an import takes to complete depends on a lot of things, including how many posts/comments are in the journal. To give you a ballpark figure that might be off by up to 100% on either side: If I personally started a brand new import right now (in my timezone, the early morning of Monday 10 Apr), I would be pleasantly surprised if it finished before Tuesday morning (24 hours or so), would expect it to finish sometime on Tuesday night or maybe even stretch all the way to Wednesday night (36-60 hours), and wouldn't start to wonder if I should poke [staff profile] mark or [personal profile] alierak to doublecheck that something hadn't gotten stuck in such a way that our monitoring didn't alert us about it until Thursday afternoon or evening (100+ hours).

All of those time estimates, by the way, assume a relatively uncomplicated job that succeeds on the first try. When the site tries again after a failure, it includes a delay that increases after each failure in case the failure was due to transient network issues. So, I know some of you started an import at the end of last week and it's still running: some of you are trying to import very large journals, and some of you ran into errors along the way and are in a retry wait loop. Again: if you haven't gotten the final error message in your inbox (and it will tell you it's the final error), it's still chugging along.

You do not have to leave the importer page open or stay logged into Dreamwidth until your import finishes. (You do have to avoid changing your LJ password until the job is done, or it will fail.) You can close the window/tab and go off and explore Dreamwidth; the movers will be along in a little while with your stuff.

The tl;dr version of my usual longwinded babble: IMPORTER VERY BUSY. MANY PEOPLE MOVING IN. LIKE ON DORM OR APARTMENT MOVE-IN DAY, FREIGHT ELEVATORS VERY SLOW. BUILDING OWNERS RUNNING FREIGHT ELEVATORS AS FAST AS POSSIBLE AND APOLOGIZE FOR THE WAIT.

A housewarming glass of champagne/sparkling cider/fancy handmade soda for all! Welcome to the neighborhood.

EDIT, 10 Apr 2017 7:15PM EDT: the importer is not the only thing that is very busy today! I'm trying to get to all the comments here, but keep getting dragged off to handle other stuff (and will be knocking off for the night soon). If you have a technical support problem, it will probably be faster to open a support request, where there's less likelihood that it will get overlooked in the sea of comments.

Oh, I completely get that. I'm amazed at what you've managed to do considering how many people are currently jumping off the wreck that is LJ... Thank you so much for all your work.

Holy wow. This makes me excited to be here. The loss of a permanent account hurts though.

Yeah, my lj permanent account paid itself off over ten years ago but it's still a bit sad. I remember putting the check addressed to LJ in the mail when I was a teen still.

Ugh, likewise. Mine was an early high school graduation present to myself. I will say that it helps me to remember that Dreamwidth is a sit I want to actively support with more money, but I do still feel the loss.

I was fifteen or so! IMAGINE THAT ONLINE. FOREVER. I privated the entries a long time ago but it feels like I have a horribly embarrassing ghost locked up inside the journal.

I like DW and I've been using it for a while. It keeps the format I enjoy with a lot of the things I didn't enjoy gone. Also a lot more ease of use and nice features like the double sticky.

And I feel you about the accounts.

'Oh no... oh no' as you read old entries.

Thank you so much to you and mark both for starting DW and never giving up on it! LJ was my first home on the internet, but DW really is my home now. And the venture capital startup model can go -- whistle.

LJ was my first home on the Internet too (aside from a MUX/IRC!). I spent a lot of years pouring everything I had into LJ -- blood, sweat, and tears.

But here we are and here we'll stay. I love our new little corner of the Internet and I'm glad you're here. :)

Speaking for myself, I thank you for coming out of hiding. Especially for this. No reply needed.

Thank you SO MUCH for starting Dreamwidth. I don't know what I'd do if y'all didn't exist.
(PS: you do not have to respond to this comment. You are swamped.)

We totally can scale up usage with zero problems

Just don't sell DW to Russian government, like LJ owners did and don't treat Tor/i2p connections badly, like Google does...

In practice, we sometimes need to restrict accessing the site via Tor, because much of the malicious traffic we get comes through Tor: not all Tor traffic is malicious, of course, but 99% of our malicious traffic comes via Tor and sometimes we have to implement restrictions in order to stop it.

May be it's better to create dreamwidthXXXXX.onion and handle Tor traffic as a native Tor service?

[personal profile] burbilog 2017-04-10 03:15 pm (UTC)(link)
Yes, consider this: if you serve native Tor and block Tor exit nodes (these are anyway could be malicious and could do much more harm besides dumb DDoS) then your main system is not going to be affected anymore by Tor attacks. On other hand, if someone somehow DDoSes your Tor subsystem, only that service is going to be down.

From Tor FAQ:

What about distributed denial of service attacks?

Distributed denial of service (DDoS) attacks typically rely on having a group of thousands of computers all sending floods of traffic to a victim. Since the goal is to overpower the bandwidth of the victim, they typically send UDP packets since those don't require handshakes or coordination.

But because Tor only transports correctly formed TCP streams, not all IP packets, you cannot send UDP packets over Tor. (You can't do specialized forms of this attack like SYN flooding either.) So ordinary DDoS attacks are not possible over Tor. Tor also doesn't allow bandwidth amplification attacks against external sites: you need to send in a byte for every byte that the Tor network will send to your destination. So in general, attackers who control enough bandwidth to launch an effective DDoS attack can do it just fine without Tor.
