My ATLAS tasks switched to the fallback server ccfrontier.in2p3.fr. Looks like lcgft-atlas.gridpp.rl.ac.uk is down. |

You are too fast :) This server has been permanently shut down today, and earlier I changed things so that new WU do not use it. The existing WU should fallover to one of the other servers so tasks should not fail. |

Permanently? That means, I can remove that server from my proxy configuration? Is ccfrontier.in2p3.fr the new preferred server or still a fallback? Or does ATLAS now get a Cloudflare proxy like CMS (cms-frontier.openhtc.io)? |

Yes, permanently. ccfrontier.in2p3.fr and atlasfrontier-ai.cern.ch are the only two Frontier servers used by ATLAS now. Where do you have this server in your configuration? I don't think it's possible to set Frontier servers yourself, and only the squid proxies are configured by the ATLAS bootstrap scripts. Frontier access is configured through an environment variable which is set automatically by the task, or in the case where someone has a proxy configured, it is set by the bootstrap script to use that proxy, eg (for the case without own proxy) FRONTIER_SERVER=(serverurl=http://atlasfrontier-ai.cern.ch:8000/atlr)(serverurl=http://atlasfrontier2-ai.cern.ch:8000/atlr)(serverurl=http://atlasfrontier1-ai.cern.ch:8000/atlr)(serverurl=http://ccfrontier.in2p3.fr:23128/ccin2p3-AtlasFrontier)(serverurl=http://ccfrontier01.in2p3.fr:23128/ccin2p3-AtlasFrontier)(serverurl=http://ccfrontier05.in2p3.fr:23128/ccin2p3-AtlasFrontier)(proxyurl=http://db-atlas-squid.ndgf.org:3128)(proxyurl=http://atlas-db-squid.grid.uio.no:3128)(proxyurl=http://dcache.ijs.si:3128)(proxyurl=http://atlasbpfrontier.cern.ch:3127)(proxyurl=http://atlasbpfrontier.fnal.gov:3127) serverurl defines the Frontier servers themselves and proxyurl the squid proxies. I agree it would be a good idea to use a Cloudflare proxy for ATLAS volunteers without their own squid. I wonder if the existing CVMFS proxies could be used for Frontier. |

Where do you have this server in your configuration? I don't think it's possible to set Frontier servers yourself, and only the squid proxies are configured by the ATLAS bootstrap scripts. I configured it as parent in my squid configuration. Nothing to worry about. It just creates a couple of statistics data. What I see from the currently running tasks is that the order of the frontier servers is different from your example. Order matters as the first server in the list will be asked first and all others will be there for failover. If you need a special order you may investigate why this is different, otherwise just ignore it. Your example: FRONTIER_SERVER=(serverurl=http://atlasfrontier-ai.cern.ch:8000/atlr)(serverurl=http://atlasfrontier2-ai.cern.ch:8000/atlr)(serverurl=http://atlasfrontier1-ai.cern.ch:8000/atlr)(serverurl=http://ccfrontier.in2p3.fr:23128/ccin2p3-AtlasFrontier)(serverurl=http://ccfrontier01.in2p3.fr:23128/ccin2p3-AtlasFrontier)(serverurl=http://ccfrontier05.in2p3.fr:23128/ccin2p3-AtlasFrontier)(proxyurl=http://db-atlas-squid.ndgf.org:3128)(proxyurl=http://atlas-db-squid.grid.uio.no:3128)(proxyurl=http://dcache.ijs.si:3128)(proxyurl=http://atlasbpfrontier.cern.ch:3127)(proxyurl=http://atlasbpfrontier.fnal.gov:3127) My local setup.sh.local (configured by the task): export FRONTIER_SERVER="(serverurl=http://ccfrontier.in2p3.fr:23128/ccin2p3-AtlasFrontier)(serverurl=http://atlasfrontier-ai.cern.ch:8000/atlr)(proxyurl=http://</censored>:3128)" I agree it would be a good idea to use a Cloudflare proxy for ATLAS volunteers without their own squid. I wonder if the existing CVMFS proxies could be used for Frontier. CMS is using CVMFS via Cloudflare but also Frontier via cms-frontier.openhtc.io:8080. For details you may contact Laurence and/or Dave Dykstra. |

http://cvmrepo.web.cern.ch/ is down it would timeout and try mirror but repeat with same ipv6 address. Could anyone report to CERN IT team? |

You can send a PM to Nils Høimyr. Maybe he reach someone tomorrow in Cern-IT. |

Sent a pm to him about this issue. In middle of retry i got message to try yum-config-manager --disable cernvm or subscription-manager repos --disable=cernvm but could not continue after using them. I will try another day. |
