			Due to a critical security vulnerability, <strong>all login nodes of the HPC systems at KIT had to be taken offline immediately</strong>.
	The login issue with bwUniCluster 3.0, which had been occurring since Friday, March 13, 2026, at 10:00 p.m., has been resolved.

			<h3>What does this mean for you?</h3>
	The cause was a software error in the parallel file system, which has since been successfully corrected.
	A patch developed for us by the manufacturer has been applied. However, we would like to point out that we cannot currently completely rule out the possibility that the problem may recur under certain circumstances.

			<ul>
	You can now log in as usual. Please check the results of your calculations and resubmit any jobs that were interrupted.
			<li><strong>Login access is currently unavailable</strong> – please refrain from further login attempts.</li>
			<li>Jobs already <strong>running in the queue are not affected</strong> and will continue as normal.</li>
			<li><strong>New jobs cannot be submitted</strong> at this time.</li>
			<li>Deletion of <strong>workspaces</strong> has been disabled.</li>
			</ul>

			<h3>Next Steps</h3>

			<p>We are working diligently to resolve the issue and will keep you informed as soon as the systems are available again. The optimistic ETA for return to service is the beginning of calendar week 29.</p>
			<p>We apologize for the inconvenience and thank you for your understanding.</p>

	~~We are currently experiencing~~ an issue on bwUniCluster 3.0 ~~that~~ ~~prevents~~ ~~users~~ ~~from~~ ~~logging~~ ~~in.~~ ~~The~~ ~~disruption~~ is ~~caused~~ by ~~a software error~~ in ~~the~~ ~~filesystem~~.		The login issue with bwUniCluster 3.0, which had been occurring since Friday, March 13, 2026, at 10:00 p.m., has been resolved.
	Our team is working intensively to resolve the problem, in close collaboration with the system’s manufacturer. At this time, we are unable to provide an exact estimate for when the issue will be fully resolved.

			The cause was a software error in the parallel file system, which has since been successfully corrected.
	We do not expect a long‑term outage; therefore, any workspaces that may have expired during the disruption should be easily restorable using ws_restore.
			A patch developed for us by the manufacturer has been applied. However, we would like to point out that we cannot currently completely rule out the possibility that the problem may recur under certain circumstances.
	<!-- Please see the [[BwUniCluster3.0/Maintenance\|maintenance]] page for more information about planned upgrades and other changes -->

			You can now log in as usual. Please check the results of your calculations and resubmit any jobs that were interrupted.
	We will inform you via the mailing list as soon as there are any updates.
