Those of you who use rdp.mcs.anl.gov (Remote Desktop server for Windows) may have noticed the disk is quite full. I need to migrate users to a new partition to free up space. This, however, requires the machine be offline during the migration. At the moment, the plan is to take the machine offline tomorrow at …

Quick summary: I just got back from the 221 data center (gee, it’s hot outside) having replaced what we suspect are bad power supplies in a Virtual Machine Host server. We isolated the issue to this specific server rebooting without offering any useful information as to why in its logs, coupled with a bad set …

A similar outage to this morning is occurring (though limited in scope at the moment since we know what *won’t* work to bring things back. Stand by…

The aforementioned outage is resolved. A disk problem took out our virtual server master around 4 AM, which took out a handful of virtual servers.

Please note, if you connect to the eduroam wireless network, you will be on a visitor network (i.e., no access to inside.anl.gov or other internal sites) the same as if you joined the Argonne-guest network. However, the connection …

Please see the below announcement from CIS on upcoming work at the end of the month. By the looks of it, the only outages you should expect over that weekend would be some business systems being unavailable. E-mail will be unaffected. WHAT ARE WE DOING? Argonne’s quarterly IT maintenance weekend is scheduled for Friday, August …

Please see the below announcement from ANL Cybersecurity. As noted, it’s recommended you disable automatic MMS retrieval on your device if you use Android. Depending on your MMS application, the instructions for doing this may vary. I’ve included instructions for two Google messaging apps. Check the settings in your SMS/MMS app if it’s not one …
