Hi! on 2019-05-16 13:00 UTC there will be a maintenance operation in one of the Wikimedia Foundation datacenter racks that affects 2 of our servers running virtual machines [0]. There is a risk that this maintenance operation can result in power loss of the servers, affecting the virtual machines running on it. However, there is no way to know for sure if there will be any outage at all. If you are an admin of any of the VMs in the list and you want the VM to be reallocated into other servers previous to the operation, please get in touch with us as soon as possible. Remember that, right now, reallocating the VM to other server means shutting down the VM briefly. Here is a list of affected virtual machines: cloudvirt1028.eqiad.wmnet: af-puppetdb01.automation-framework.eqiad.wmflabs bastion-eqiad1-02.bastion.eqiad.wmflabs fridolin.catgraph.eqiad.wmflabs cloud-puppetmaster-02.cloudinfra.eqiad.wmflabs cloudstore-dev-01.cloudstore.eqiad.wmflabs commtech-nsfw.commtech.eqiad.wmflabs clm-test-01.community-labs-monitoring.eqiad.wmflabs cyberbot-exec-iabot-01.cyberbot.eqiad.wmflabs deployment-db05.deployment-prep.eqiad.wmflabs deployment-memc05.deployment-prep.eqiad.wmflabs deployment-sca01.deployment-prep.eqiad.wmflabs deployment-pdfrender02.deployment-prep.eqiad.wmflabs ign.ign2commons.eqiad.wmflabs integration-slave-docker-1050.integration.eqiad.wmflabs integration-castor03.integration.eqiad.wmflabs api.openocr.eqiad.wmflabs osmit-umap.osmit.eqiad.wmflabs builder-envoy.packaging.eqiad.wmflabs jmm-buster.puppet.eqiad.wmflabs a11y.reading-web-staging.eqiad.wmflabs adhoc-utils01.security-tools.eqiad.wmflabs util-abogott-stretch.testlabs.eqiad.wmflabs canary1028-01.testlabs.eqiad.wmflabs stretch.thumbor.eqiad.wmflabs tools-worker-1023.tools.eqiad.wmflabs tools-proxy-04.tools.eqiad.wmflabs tools-docker-builder-06.tools.eqiad.wmflabs tools-sgewebgrid-generic-0904.tools.eqiad.wmflabs tools-sgeexec-0942.tools.eqiad.wmflabs tools-sgeexec-0941.tools.eqiad.wmflabs tools-sgeexec-0940.tools.eqiad.wmflabs tools-sgeexec-0939.tools.eqiad.wmflabs tools-sgeexec-0937.tools.eqiad.wmflabs tools-sgeexec-0929.tools.eqiad.wmflabs tools-sgeexec-0921.tools.eqiad.wmflabs tools-sgeexec-0920.tools.eqiad.wmflabs tools-sgeexec-0911.tools.eqiad.wmflabs tools-sgeexec-0909.tools.eqiad.wmflabs toolsbeta-proxy-01.toolsbeta.eqiad.wmflabs vconverter-instance.videowiki.eqiad.wmflabs perfbot.webperf.eqiad.wmflabs wdhqs-1.wikidata-history-query-service.eqiad.wmflabs cloudvirt1014.eqiad.wmnet: commonsarchive-prod.commonsarchive.eqiad.wmflabs deployment-imagescaler03.deployment-prep.eqiad.wmflabs dumps-5.dumps.eqiad.wmflabs dumps-4.dumps.eqiad.wmflabs incubator-mw.incubator.eqiad.wmflabs webperformance.integration.eqiad.wmflabs saucelabs-01.integration.eqiad.wmflabs integration-puppetmaster01.integration.eqiad.wmflabs maps-puppetmaster.maps.eqiad.wmflabs maps-wma.maps.eqiad.wmflabs mwoffliner3.mwoffliner.eqiad.wmflabs mwoffliner1.mwoffliner.eqiad.wmflabs phlogiston-5.phlogiston.eqiad.wmflabs discovery-testing-01.shiny-r.eqiad.wmflabs snuggle-enwiki-01.snuggle.eqiad.wmflabs canary-1014-01.testlabs.eqiad.wmflabs tools-sgeexec-0901.tools.eqiad.wmflabs wdqs-test.wikidata-query.eqiad.wmflabs Toolforge won't be affected by this operation.
