| 2026-03-12: Cocopedia.com is now using a new caching system that should make things faster. Please let me know if you encounter any new issues.
2026-03-15: MediaWiki has been reinstalled and the old database and files restored. It was pretty clogged up from being upgraded so many times since 2004. I am also testing out Cloudflare to see if it can prevent the 'bot assaults that took the site down last year. 2026-03-16: Special thanks to Don Barber for hosting a backup mirror of CoCopedia: https://cocopedia.dgb3.net |
