Change Of IP Address last night, Downtime

I take the unusual approach of hosting my site and Blog, on my private PC at home, acting as a Web-server. It’s the computer I name ‘Phoenix’. Because of that, the visibility of my site is only as good, as the presence of my LAN on the Internet.

At the same time, my connection to the Internet is ‘only’ a domestic DSL, which achieves speeds of up to 50Gbps. This means that my ISP, is capable of changing the IP address at any time, with which my LAN is connected to the WAN. This is a right which they have, and is referred to as conventional ‘DHCP’.

Last night, my ISP did change the IP address, with which my LAN connects to the Internet. And what this means to my readers is, that from about 2h47 until about 3h17 this morning, local time, my Blog was also off-line.

I should also note that this minor interruption to my service took place at a time, when most domestic users don’t use the Internet, but during which many customers are sleeping. Therefore, this would also have been an ideal time by conventional standards, for my ISP to carry out any maintenance they had to carry out.

But nevertheless, I apologize to any readers for the fact that during this brief interval in time, they would not have been able to access my site.

Power failure tonight, downtime.

This evening, Montreal experienced a forecast, severe thunderstorm. But what could not be forecast with certainty, was whether the power would fail, in my exact neighborhood. In fact, it did.

I take the somewhat unusual approach, of hosting my Web-site, and therefore also this blog, on my PC at home. The availability of this blog can therefore not be any better, than the availability of my PC, to the Internet. Therefore, this site and blog were briefly offline, from about 19h00 until 20h00. I apologize for any inconvenience to my readers.

Planned Power Cut Today

One of the subjects I wrote about in past months, was that My power utility had been planning to cut power to my home, briefly, to perform work on the -distribution system. This had to do with our wireless power meters, that needed to be replaced.

Because the linemen knocked on my door, and forewarned me of the power cut, in order to avoid any file-system corruption, I actually shut down all my computers, one of which acts as my Web-server.

As a result of my shutting the computers down, my site and blog were off-line from about 13h30 until 14h20 this afternoon. I apologize for any inconvenience to my readers.

The actual power-cut only lasted approximately 5 minutes, but because I did not know the exact timing with which it would take place, I was cautious and shut down my computers at 13h30 already.

This time around, the X-server on the computer named ‘Phoenix’ took 2 attempts to restart.

At least this power-cut resolved an outstanding issue.

Kernel Update today, Downtime, Multiple Reboot-Attempts

Today, the PC which is hosting my site and blog, which I name ‘Phoenix’, received a kernel update.

Debian Team has not been following standard guidelines in their propagation of kernel updates, as the last 3 updates produced the same kernel-version number:

 


3.16.0-6-amd64

 

Because even Linux computers require a reboot after a kernel-update, this blog was temporarily off-line from about 13h05 until 13h25. I apologize for any inconvenience to my readers.

There is a fact about the build of Linux on this computer which I should bring up. I have the following on-board graphics-chip:

 


GeForce 6150SE nForce 430/integrated/SSE2

 

And this proprietary graphics driver is the only one, capable of working with the said graphics-chip:

 


NVIDIA 304.137

 

The graphics driver is installed from standard Debian repositories.

Somewhere between these software-packages there is a problem, which Debian Team has never been aware of, but which has existed ever since I installed Debian / Jessie on this computer. Directly after a reboot, the ability of the X-server to start, is not reliable. Sometimes, the X-server starts on the first try, but on other occasions I need to make 7 reboot attempts, before the X-server will start, and from one reboot-attempt to the next, I change nothing.

Once the X-server has started successfully, this graphics-chip will work 100% for 30 days !

I have been reluctant to point this out for the past few years, because if a Debian developer finds out about it, he will try to fix this problem. And when he does, he will brick my computer.

This afternoon, 7 reboots were in fact required, before the X-server started. That is why the reboot-procedure took 20 minutes of time.
