Hello all, your friendly Ozblogistan Tyrant here.
Tonight I am going to be moving to new servers. All the Ozblogistan sites (Andrew Norton, Catallaxy Files, Club Troppo, Henry’s Lore, John Quiggin, Larvatus Prodeo, Sensible Social Policy and Skepticlawyer) will be offline during the move.
I am making this move because performance has been steadily worsening in the past few months. My current provider, Linode, have more powerful plans available. However our problem is not that we need more RAM or more powerful virtual CPUs. Our performance is constrained mostly by disk performance.
Our new home, DigitalOcean, build their systems using much faster disks than Linode currently do. I also considered hosting with Australian provider OrionVM, but Australian bandwidth is simply too expensive. Absurdly so, compared to everywhere else.
Starting after 7.30pm Western Australian time, Ozblogistan will be down for up to several hours. Hopefully you all have better things to do on a Friday night than mash the F5 key.
Approximately 4 hours ago, Ozblogistan began to receive a very high level of traffic. During this period my performance tracking tools stopped working so it is difficult to tell how much traffic was received during the period.
A few minutes ago I kicked over our web server to reset all connections, which resolved this matter last time. This time too, apparently.
There are three possibilities:
- Misconfiguration of the web server software
- A badly behaved indexer program
- A denial of service attack
I am confident that the server is correctly configured, but I cannot eliminate the possibility that I am misinterpreting the available performance records. That kicking the server over “fixes” the problem might suggest this possibility.
If there was a badly behaved indexing program crawling all Ozblogistan sites, it should have turned up in my Cloudflare dashboard which, so far, it has not.
The odd man out in the Ozblogistan network is Catallaxy Files. The Cat is the only site currently not “behind” Cloudflare’s protective service. If we were receiving the loving ministrations of a badly behaved indexing program, then that program was exclusively crawling the Cat.
The unhappiest possibility is that this was a denial-of-service attack; again, directed against the Cat. Sometime in the next few days I expect that Catallaxy Files will be placed behind Cloudflare along with the other Ozblogistan sites and that this will prevent any such attacks from being successful.
Well, that’s it, folks. Please resume your usual blogging and commenting.
If you see this message, you’re on the new servers at the original providers.
Moses ain’t got nothing on me.
Hello all, your friendly Ozblogistan Tyrant speaking.
Unfortunately the technical issues with Page.ly have grown more and more severe in the past two days.
So I am now preparing to perform the migration of shame: Ozblogistan will be returning to my own personal supervision for the foreseeable future.
That you can see this post means you’re on the new server. Welcome.
There will be glitches — duplicates and the like.
Sorry about the disruption, but I hoped you all enjoyed the kittens and the dalek.
Hello everyone, your friendly Ozblogistan Tyrant here.
Ozblogistan was moved to new servers on Monday night by some subcontractors. The ensuing few days have been a mess because the move was only incompletely successful. In particular, bloggers have been unable to log into the wordpress backend to write posts or moderate comments.
This morning a threw a switch and it appears as though we are slowly coming back online. I’m very sorry for the disruption.
Hello all, your friendly Ozblogistan Tyrant here.
This weekend I will be performing one of the biggest changes made to Ozblogistan in several years.
I am moving the site from its current home to a new one.
The new service is a company specialising in WordPress hosting. They will be taking responsibility for all the scut-work of making the site go.
Once the move is finalised, I expect that Ozblogistan will be snappier than it is now. I also won’t have to worry about fixing security problems, doing backups, finding out why plugin X has stopped working, working out why the site has suddenly died and so on. These will now be responsibilities I can delegate to the providers.
This has been in the works for some time. While I was a student I could afford the time it takes to keep Ozblogistan working relatively smoothly. As a professional I no longer have that time. So it makes sense to hire other professionals to do it for me.
The security problem we had a few weeks ago (and which is still causing false positives) was the straw that broke the camel’s back.
Moving providers is never pretty. Things are going to break this weekend. And various things will probably appear broken into the new week. It’s all for the good. Ozblogistan will shine out ever brighter.
Update Saturday 2:17PM WST: Failure. I will probably have to try again on Monday night. I’ve re-enabled comments.
Hello all, your friendly Ozblogistan Tyrant here, abusing my multisite posting powers.
This morning I received two independent reports of trojan warnings being given for two different Ozblogistan websites.
After investigation, I have determined that the server was automatically compromised, presumably by a brand new attack (since we just 2 days ago updated to WordPress 3.4.1), and a trojan inserted into various parts of WordPress.
I have identified and replaced the affected files with clean copies, and you should see no more warnings.
Those who want the gruesome details can learn more.
Hello everyone, it’s your friendly Ozblogistan Tyrant here.
I plan to migrate our servers to a different data centre tonight. There will be some disruption during the move, and it may take time for your DNS records to be updated.
We’re moving from the Fremont data centre, which has turned out to be about as reliable as a Ford Pinto, to the Dallas data centre (I look forward to your big-hats-and-oil jokes).
John Quiggin has upped stumps at his previous provider Joyent and moved in alongside Club Troppo, Catallaxy Files, Larvatus Prodeo and other leading Australian blogs here at Ozblogistan.
John is one of the long standing fixtures of the Australian blogging scene and it is nice to have him aboard.
