Hi, everyone. Hope your summer has started out well and you’re enjoying the 90 degree weather and the humidity. Mmmm… swampy. Anyway, I wanted to make you all aware of an upcoming maintenance weekend. During the weekend of Friday, June 18 to Sunday, June 20, we need to take various components of the infrastructure offline …

Hi, everybody.  I was originally going to send this as a more targeted email to users who I know were affected by this issue, but it turns out the scope is broader than that.  But it’s also a nice opportunity to remind everyone to make sure their info is up to date and what they …

In going over the upgrade process, we found we were kicking a particular can down the road and would run into the need to have another outage to get us where we need to be. So rather than prolong the inevitable, we’ve come up with a new process wherein all the servers will be updated …

The legacy gitlab servers are still operational and in need of updates.  We have two git servers in Legacy: gitlab.cels.anl.gov which is internal only (no access from outside Argonne) xgitlab.cels.anl.gov which is the one most of you are using. We will be taking down gitlab.cels.anl.gov on Thursday morning at 9AM to get it up to …

Hi, everyone! It’s been a long time since I’ve done one of these proper updates on current services and upcoming changes, and there’s a fair bit to unpack, so I’m going to take a slightly different approach to make sure the relevant info is front-loaded and you can read on for more details and musings …

The computers running login.mcs.anl.gov (the Legacy MCS login nodes) are running an OS that will reach end of life at the end of the month. As such, we’ll be turning off the ability to SSH from offsite on Monday, May 17, 2021. This will not affect SSH from on-site or via VPN. You can continue …

Hi, everyone. I’m in the process of writing a bigger update and newsletter, but wanted to announce this separately since it’s significant and shouldn’t wait until I wordsmith the newsletter into existence. We have a new confluence server! confluence.cels.anl.gov is up in GCE and ready for your use.  It uses your GCE/Argonne account (unlike the …

In preparation for an update to the existing Jenkins server at jenkins.cels.anl.gov we need to run a full backup. While this backup runs, new jobs will sit in the queue and will not be processed. They will run when the backup is complete. We’re starting the backup at 5PM tomorrow (Friday, April 9). We hope/expect …

The CELS Jira service (jira.cels.anl.gov) will be unavailable this evening (2/24) due to emergency maintenance starting at 5:00 PM CST until 7:00PM CST.
