Image server overload 2005-03
In March 2005 the main Wikimedia image server became overloaded, seeing too many read requests to keep up. As a result the images were temporarily removed from several very-frequently-used templates to decrease the load and assist with site performance. In addition to the temporary image removals the following work is happening:
- A new server to be used for this if necessary, and as a database server if not, is being purchased. This will have 1.2TB of disk space using six 400GB SATA drives and 8 or 16GB of RAM. The current machine has just under 1TB in RAID 5 and 1GB of RAM.
- Some of the image-size checking which is done by loading images off the image server is going to be moved to database fields so the image server doesn't need to read the images to get the information with each page view.
- One developer is writing a distributed image/blob tool which will let us spread the images around a large number of machines.
- A cache to help reduce the amount of image loading has been added but didn't make sufficient difference.
All projects are affected and it would be helpful, and make page loading faster, if images in templates used by more than about 500 articles were temporarily removed. Please add an entry on this page so we can easily undo this when it is no longer necessary.

editen wikipedia
editTo reduce server load, I have commented out images on the following pages. Feel free to revert any or all of these edits using the rollback feature. I promise I won't be offended. - Mark Ryan
- Many templates on this list centrally located at en:Wikipedia:Template_messages/Image_namespace -- en:User:dbroadwell
Template:United States - the US flag up the top right corner (I also added a colspan=2 in there, so a rollback is the best way to go back)Template:MetaPicstub - the cell and image on the leftTemplate:Message box - cell and image againTemplate:Stub - imageTemplate:Substub - cell and imageTemplate:Expansion - cell and imageTemplate:NowCommons - cell and imageMain Page - the "Other languages" image up the top right hand corner- en:Template talk:MetaPicstub - request to remove images for those used by about 500 or more articles.

editImages which are candidates for temporary removal
editUse count and image name for the most used en images, many of which are probably used in templates and easy to temporarily remove.

editFirst group are believed done and showing up only because they don't get removed from the list until the articles using the templates are changed. Second group is pending.
