Distributed Proofreaders is on Twitter! Now you can keep up with DP’s milestones, new blog posts, and other news. Just follow @DProofreaders to stay in the know.

Distributed Proofreaders is back!

March 8, 2014

Our OS Upgrade/Server Migration is now complete.

Because we have moved to new hardware and a newer version of the operating system, there may be some minor issues left to resolve. If you encounter anything unusual, please let us know in this thread.

If you’re having trouble reaching the site, please try clearing your cache, removing cookies for pgdp.net, and/or restarting your browser.

Thanks to all the squirrels for their assistance in making this major transition happen, and thanks again to our volunteers for waiting patiently while we accomplished this task.

Please check on the DP forums over the next few days for a post with additional details and information once I’ve returned from being on-site.

Friday Update on our DP Server Status

March 7, 2014

As of 7pm EST Thursday, the new server is in place at the hosting site and squirrels other than donovan have been able to access the system and begin the last stages of configuration, tweaking, validation, etc.

So far, the majority of the site is functioning as expected, with the exception of the wiki, possibly the mailing lists, and some mail functions. Our current focus is to ensure that all the back-end infrastructure is in place and correctly configured.

We’ll continue to provide updates on our progress and expect DP to be back in business fairly soon.

Thanks again for your patience! We’re definitely getting closer!


Brief Update on our Progress

March 5, 2014

We’re making progress!

Prod6 has stopped sulking and is once again communicating with us. As a precautionary measure, we’ve taken full backups of it, and we’re now copying the production data over to the new machine which will become our new production server.

We’ll continue to update you on our progress.

Thanks for your patience and good will!


Distributed Proofreaders Outage Update: Monday, March 3, 2014

March 3, 2014

Unfortunately we have not been able to bring the server (prod6) back online remotely. After evaluation, we have decided to prepare a new server and migrate DP to that machine earlier than originally planned.

As noted previously, this is one of two identical machines graciously donated by Tom Kowal.

Prod6 has (literally) served DP well since 2006 and was slated for replacement in summer 2014 but, given the current situation, making that transition now should minimize the total disruption of service.

The new machine (prod7) has been in preparation since early this morning, already has the OS upgrade on it, and is being prepared/configured with the necessary software. In addition to being more recent hardware, prod7 also gives us two additional drive bays, a battery-backup unit on the drive controller, twice the RAM, and twice as many cpu cores as we currently have with prod6. Those factors combined with a move to the ext4 filesystem should make the server a bit more responsive during heavy load.

Brief stats: 2x Xeon @2.00GHz, 4 cores each. 8G RAM. 8x 300G drives (2 as RAID mirror for the OS, 4 as RAID-5 for the data, and 2 hot spares).

Once the build-out is complete, the new hardware will be transported on-site and we will begin transferring the databases, project files, etc. over. This may take an extended time, as we do not yet know exactly what conditions we will be working under.

Transport and on-site work is tentatively scheduled to take place tomorrow (Tuesday, March 4).

Once again, thanks for your patience. We’re working hard to bring you an improved experience.
