Today the webserver with the Caedmon webcam pointing to the Acre and the James Graham Building was restarted again. It had been off for an unknown time, probably due to a temporary shut-down a short while ago. Since I no longer have an office in which this webcam is located, I was not able to immediately restart it after I had noticed the shut-down. Another issue hid this shutdown from me for a while: due to a wrong configuration of the 2nd webcam server (which points to the parking lot between Priestley and Caedmin), the picture of that server replaced the one from the main webcam, with the result that the supervisory process (which checks if there is no new image within 24 hours) has not detected a lack of images, and therefore has not sent a notification about the webcam outage.
This has now been fixed, and both webcams run properly as intended. The Headingley Caedmon Webcam has indeed been running for several months without me ever visiting or maintaining the server.

One week camera outage
The webcam (with its PC) had been running continuously since March 2010 - quite robustly without any problems. On Friday 23.July 2010 in the afternoon a brief power outage occurred at the Headingley campus. And after that the webcam image was no longer updated. I had no opportunity to fix this problem before now, so the cam image remained steady for more than a week - apologies!
When I checked today, the computer was completely shut-down. It might have also been that the PC was shutdown by someone, unrelated to the power outage. Restarting it had a slight problem, due to two different webcam software version that had been installed. Version 1.0.5 was the one that ran now properly. In any case the camera is up and running now fine.

Server update - camera is out for a while...
On Sunday, 13.9., an upgrade of the basic server scripting components was carried out. For some reason, this affected the web cam software as well. I am investigating what the problem is.

Camera Outage
During the summer break, the camera had been running fine, until on 21.August, 7:04, the server restarted. I will have to identify why this happened. Since I was not here to restart also the capture software, the web cam website only displayed the last captured image from that morning.
It is up and running now, currently capturing at a rate of 1 picture per minute, without saving the image series.

Capture Outage Today
Today at 11:20 I had to re-login on the capture PC with another user account name, and therefore had to shut-down and restart the camera capture software. In the course of starting it up, I had put an incorrect FTP password in the parameters... and so the images were captured and stored in a series, but were not uploaded to the webserver. Apologies for this mishap!
This makes me consider to develop a remote control for the camera captue software. I noticed the problem already around 12:30, but was unable to fix it as I was at an out-of-office location. Such a remote control could be web-based and would allow to reconfigure the camera capture module. The next version will have such a remote control.

Update of Server Scripts
The increased demand of the image capture on our server due to the link to the Leeds Met public web site made it necessary to provide an update to the server code which would improve the "garbage collection" of temporary image files. This has now been implemented. There was a brief outage during the transition to the new version. If there appears a "not found" error, just refresh the whole page, and the image should be there again.

Webcam Outage
On 2. July 2009, 7:05, the PC was for some reason rebooting. Since I was not available for logging in, the image capture had been interrupted since then, and it only resumed after I restarted the PC yesterday on Monday, 6.July.
The image capture is now running at an increased frame rate of 1 pic per minute. There is no longer a storing of each image, as the time lapse sequence for building the marquee has been completed. I will switch the recording on again next week for the graduation ceremonies, with an increased framerate of one picture every 30 seconds.
