MT vulnerability
There is a vulnerability in MT’s send-entry program (that is used by blogs that want to have an ‘e-mail this article’ option) that could allow spammers to use it.
MT’s article may be found here.
They have issued a fixed mt-send-entry.cgi file (the file affected). All the MT users hosting here at Blog Househave been upgraded. I decided it would be easier just to upgrade everyone than to bug you to do it. 
However, MT recommends that if you are not using the send-entry option that you remove that file entirely. I would second their recommendation, since their upgrade is more secure but not completely secure.
Many thanks to Wizbang for the warning.
Backbone problem
Sorry about the lack of connectivity this morning. The servers were up but there was a router problem upstream of our datacenter.
The info I got was that there was a bug in the cisco IOS that their routers were using that caused a line card error, so they had to do an emergency IOS update on their routers. Now you know as much as I do.
I suspect the problem was caused by a DOS attack since that is reason for the latest IOS update. Our datacenter updated its routers’ IOS a few days after the update came out, so please excuse me while I go cuss out that upstream who should have done the same.
MT users
We’ve had a server problem and will need to reinstall some modules necessary for MT. We should be back to normal soon (I hope). Sorry!
[update] Still working on it. You haven’t been forgotten!
[update] This is caused by a (automatic) CPanel update that has messed things up. We are still working on it.
We now should be back to normal. Let me know if you have any problems!
Routers
The Cisco routers and switches to our server are being upgraded due to a security vulnerability (to DOS attack) that was found by Cisco.
More information here for the techie types.
If you’ve been unable to reach your site, this is probably the cause. The sites have not been down, just unreachable from some places.
Sorry for any inconvenience.
My e-mail program (the one I use at home) has been having a few problems. I’m pretty sure I haven’t lost any e-mails but I had some previously invisible ones suddenly show up when I fixed it.
So, just in case… if you sent me an e-mail and I haven’t replied, please send it again or leave a comment here! Thanks.
