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.
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.
Last night the Ozblogistan network slowed down and then began to “yo-yo” — stop working and then reappear cyclically.
I have been becoming increasingly dissatisfied with WPEngine’s reliability and service. Tis was the straw that broke the camel’s back. So I began a crash move of the network to a new hosting service, Page.ly.
That is why the site was unavailable last night and this morning, and why you first saw kittens and then a little moving truck.
Page.ly’s service has already shown itself to be much better than WPEngine’s; however they have reported back that migration is going slowly because the WPEngine servers periodically drop the connection they’re using to download files.
Their advice was to switch back to WPEngine’s servers for today. Any posts or comments from today could then be migrated using the WXR import/export facility built into WordPress.
So here we are, temporarily back at WPEngine. Tonight I and the Page.ly staff will try the move again.
A few hours ago WPEngine finally traced the problem back the recent comments widget on Skepticlawyer and Catallaxy Files. I’ve disabled those for now. (Amazing how much their service has improved, now that I’m leaving).
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.
