While we continue monitoring the situation with the CloudLinux Network, we highly appreciate your patience. Thank you for staying with us, for your understanding. Right now, the ongoing issues with the CLN have been resolved. If you still experience some issues, please reach out to our Support team; we are glad to help.
We would like to shed more light on what has happened with the CLN during recent events. Recently, we've been migrating our CLN backend from Spacewalk to new software and updating the rest of the backend. The migration itself went successfully, and we did see some progress compared to Spacewalk's performance right away. However, the newer version had some issues, causing configuration problems on the CLN end. Reverting the upgrade would bring back older "legacy" issues that Spacewalk had, so the best course of action was to proceed further and resolve any new problems that we encounter.
Usually, the service can handle load spikes rather well, RHN Proxy Server can handle incoming requests and distribute them between CLN services. Moreover, caching helps us to ease the load even more. While we were resolving those problems, the overall load on the CLN has unexpectedly increased since the cache was cleared during the upgrade.
When the load spikes happen, we had to enable limits on the simultaneous connections (up to 500, and then up to 800 connections). This has stabilized the network issues and helped the majority of the customers to successfully update/register the system.
Rest assured that we will make adjustments to our infrastructure and software update process to avoid such situations in the future.
