Update - The situation around CLN Services is improving; we have increased the number of simultaneous connections from 500 to 800. We hear back from the customers about the successful registration of their servers. We'll continue monitoring the situation, and we will keep you posted.

Update - We regret to inform you that there are still some ongoing issues with the CloudLinux Network in place. We've mobilized all our Development & Infrastructure resources to resolve all the issues for good, and we will let you know as soon as the CLN is up and running again.

Meanwhile, we have some good news. We've managed to stabilize a limited number of concurrent connections to the CloudLinux Network, up to 500 at the same time. What this means for end-users is that it is possible to complete the yum transaction/register a server/etc. when there are free connection slots available.
For example, when you register a CloudLinux OS server, you take up one slot of 500. Once the registration is over, it becomes available to everyone else.

Several reports from our customers show that running yum transactions/registration commands a couple of times helps to finish them. If you can hold off with the registration/update, we advise waiting until we confirm that the CLN services are fully restored.
