I can't access diychristmas.org right now (12 noon August 7 through comcast), "503 Service Unavaiable".
If a massive amount of data were uploaded to MediaWiki, would it slow down the site for a long time?
Yes, uploading a massive amount of data to MediaWiki can slow down the site significantly. The delay depends on server hardware, database indexing, and background job queues processing the new pages and file uploads.
Why the Slowdown Happens
- Database Indexing: MediaWiki updates search tables and link tracking for every new page.
- Job Queue Backlog: Heavy tasks like image scaling or template updates go into a queue and use server power over time.
- PHP and Database Load: High request volume during a bulk import maxes out CPU and memory.
Because MediaWiki runs "run-jobs-on-visit" by default, every time you or a user tries to view a page right now, the server attempts to process the heavy backlog of your
1,583 graphic files (generating image thumbnails, updating link tables, and metadata). This kills your server's CPU and memory, triggering the 503 response.
So, how long will the site be this slow?
If you do not change anything, the site could remain slow or completely offline for
several hours to days, depending on your server's hardware.
The website will not fix itself until MediaWiki finishes processing the backlog for all
1,583 graphic files. Because the site is currently throwing 503 errors, the automatic system is likely stuck in a loop—crashing the server, restarting, trying to process a file, and crashing again.
