New serverIs setup and functional.
Storing submission resultsWill be enabled in the next 5-7 days, however, all submissions will be regraded once a new website is pushed to production (see previous updates).
New websiteI'm (slowly) working on re-designing the website (minor visual updates, and major code refactoring). The current design is not sustainable - full of old technology and spaghetti code.

New serverJust received a (VERY) powerful server from a z-trening member (honoring his desire to stay anonymous :) ) - Thank you! (I feel so proud :P)
My plan is to try to setup the new machine and push a dev version of the new website this weekend.
Will need to re-calibrate the grader due to different specs of the the machine.

GraderI have implemented a totally new grader based on isolate. I'm still working on fine-tuning the grader, thus the grading results are not stored in the database. Also, you might encounter some glithches from time to time. I will be open sourcing the code after a thorough cleanup. Still looking for a right licence though.
Next stepsMost likely, after I'm satisfied with the grader, I will be re-grading all submissions. This is to ensure the accuracy of the fastest solutions. This, however, might result in failure of some submissions that have previously passed all the tests. In some cases, due to update of the compilers, some previous submissions might not even compile. The number of such cases is relatively small, and I will implement a mechanism for the users to be notified of such cases, and given chance to modify the code and re-submit. This would typically involve adding missing includes, and changing variable names not to use reserved keywords.
Suggestions and feedbackI'm open to any suggestions. Let's use this forum board for discussion.

StatusI think most of the pages are correctly served now. Registration, password reset, etc.. should all work. If you encounter an error, please email me at email@example.com
GradingExpected to become functional in the next 2 weeks
Z-Trening (Codah Club) is back!
Site functionalityI have managed to recover all data, from all old z-training servers. In the meantime, many things have changed, and z-training doesn't just run out of the box :) Recovering the full functionality (and possibly adding new features) will take some time, so please be patient. I'll try to keep the list below (current status and planned work) up to date.
Current status- New server built (more powerful than the old 4 servers combined...)
- Latest production version of PHP code was deployed - full of deprecated PHP code, and constants specific to the previous setup.
- Production code from the other servers (grading, storage, etc..) is currently being deployed.
Next steps0. Get rid of the PHP fatal errors (make sure all pages are served). Basically, going throigh the codebase, fixing the depricated functions, and old specific constants.
1. Recover grading functionality (needs grading and storage services refactored).
2. Recover chat (needs some redesign b/c of depricated memcache functions)
Call for helpI expect to bring all (most) of the functionality up in not too distant future. The code I wrote 10+ years ago needs serious refactoring (or full rewrite in some cases). Both PHP and C++ (main languages used) had been greatly modernized, and I might have learned a thing or two (not more) about software engineering in the meantime. So my plan is to slowly re-implement feature by feature, with more efficient and better implementation, adding new features in the meantime. Any help from previous z-training users would be GREATLY APPRECIATED.
One last thingSeems that someone had grabbed z-training.net in the meantime :( I never liked the .net extension anyways, so I decided to re-brand the website as Codah Club, where Codah is pronounced exactly the same as my fellow Bostonians pronounce 'Coder'.
Also, I won't send mass emails, to let people know that the site is up again until it's fully functional. If you know other users, let them know that we are back in business.
