[World Community Grid] Down wegens werkzaamheden datacenter

[KuuKe]

DPC-ers,

Volgens deze thread op het forum van WCG gaat het datacenter waar de WCG-servers staan van 7 december 2024 tot 3 januari 2025 wegens werkzaamheden op "zwart".

- IMPORTANT: We have been notified of an extended downtime at SHARCNET facility for construction lasting from December 9th, 2024, to January 3rd, 2025. There will be no power and no cooling during this time. We are exploring temporary migration to another site. We will provide an update on what downtime if any can be expected to start on December 9th, 2024. Overall, this upgrade should provide further improvements to the WCG capacity.
- Bandwidth has been improved thanks to hosting staff at SHARCNET. In addition, we have more and better hardware devoted to handling downloads and uploads, and a more competent load balancer.
- ARP1 will resume in limited quantities over the next few days. We will make an effort to focus on extremes as suggested in the forums and test the imposed rate limits on workunit production as well as total bandwidth of all clients and number of connections per client for ARP1 file transfer specifically.
- Forums were down earlier today for an extended period, they are back up now and we apologize for the slow response.

De genoemde 9 december is inmiddels al vervroegd naar 7 december.

And its down tot 3 januari:

- We are making final preparations to power down. Before powering off all VMs and the storage servers, we will kill all traffic at the load balancer so we can allow the filesystems and databases to settle before taking a final backup.

- When we kill traffic at the load balancer overnight on Dec. 6, there will be no access to the website, forums, BOINC scheduler, BOINC uploads, or BOINC downloads.

- We have transferred database backups for BOINC and the website/forums, as well as all source code offsite. We will be transferring the final backups overnight as well.

- Today (Dec 6), we have been taking snapshots of all production VMs and sometime this evening we should have all instances that make up our backend infrastructure backed up as snapshots, ready to deploy from resilient storage if there are any issues powering up our instances when we are back online in January.

- We will be working on the new project (Mapping Arthritis Markers), long-standing issues with device synchronization between the website and BOINC databases, server status page, real-time stats API, and a new look for the forums as well as new badges during the downtime. We look forward to sharing the results of the data center refresh with you in the New Year - thank you for your support and happy holidays!
