When I publish a post here, the site overloads in just seconds. Often before the WP editing page can update. Then users are quickly locked out as the site hits CPU, memory, and I/O use limits. The really annoying part is I too am locked out of WP Admin.
Ready For Battle
With PHP processes maxed out and being created faster than I can kill them, it’s a problem. The quick fix is to shut the site down. So, you see a page saying the site is temporarily closed. This is not a good option. Continue reading →
Yesterday was hectic day for the management of this blog. Between noon and about 2 PM PT the hosting server was overloaded with requests. Memory and I/O maxed out preventing viewing or management of the blog.
The Looking Glass Sim
So, new tools have been added and more IP addresses have been blocked. Unfortunately Go Daddy’s metrics tools do not provide the information needed to deal with an attack in real time. So, it is an arduous process of downloading and analyzing logs. But, with I/O maxed out one cannot download the logs…
Also, most of the standard ‘go-away’ tactics weren’t working. So, I had to learn new ways to regain control. So, when I am fighting off an attack you may see a B&W page announcing the site is down for maintenance. I may pretty the page up… or not. I can usually recover in a few minutes once I take the site down. So, if you see the page, check back in an hour or so.
I’ll be adding more tools so I can more quickly find the attack source and block it. Most of these attacks seem to be scrapping the site for content. Now that I’ve blocked image leeching, using my images by linking to this server, the images are being downloaded using up a LOT of bandwidth. I wouldn’t mind that much except like The Flash they try to grab everything at hyper-speed.
Let me know if you start having problems with this site. I have been upgrading the security. About 2 or 3 PM each day I see the site slammed by remote sites sucking gigabytes of content out of my site. I’m not sure why they would want it. Nor do I mind that they take it. I do mind that they overload the web server I use and make the site way slow. So, I come in each day and disconnect those that are behaving like bots… continuous dozens-of-requests per second.
On The Sunny Side of the Street
I’ve been changing robots.txt and adding ‘slow down’ instructions for search engines. That helps with the big well mannered engines. But, not the problem bots that have been hitting.
I’ve been blocking the networks the most abusive bots use. But, doing that without restricting legitimate users is complicated. So, it isn’t a good solution. Neither is blocking individual IP addresses. The bad guys just change IP.
So, now I am trying some new software. It is in learning mode. So, I’m ‘completely’ sure what all it will decide to do.
The blog Mesh Body Addicts is making the news. SL Blogger Support (Canary Beck) has an article about its success, 85,000 page views per month. The article is about blogs that serve a niche. See: How one Second Life blogger niched her blog.
Um certo cais A certain pier
Thinking about the idea of making a niche blog they omit a major point. In a changing world, your niche may, likely will, become passé or vanish altogether. I used to cover viewers in great detail. If a person was considering changing to a new viewer, this was the blog to read before changing. But, with the arrival of Oz Linden and enforcement of the ‘shared experience’ concept the Lab has pretty much taken control of viewer development. The whole field of viewer development changed, at least for what it means to me. Continue reading →
A new version of WordPress is out (4.2.3). It is a security update. I want to install it. That means I am backing up my blog so I can unwind the update if I have to. I learned long ago that depending on the hosting company’s backups is too risky.
This means the blog may be down for a few minutes or maybe just glitchy now and then. I have over 12,000 files to download and the database. It takes some time.
Flickr™ has changed the embed code they provide people for displaying Flickr images. That meant I had to change how I embed their images in the blog. I’ll explain some of what you can do with the new embed code. There is a discussion at Flickr about the new code here: New version of Flickr’s embed code.
City of the Ancient Gods
Surely, you have noticed I use more Flickr images these days. It saves me time and there are so many gorgeous images from Second Life™. Taking the time to find gorgeous places and get great photos… it was becoming work. Embedding an image is easier. Continue reading →
