This is related to the current server migrations. Please see
this topic and the
status blog for an explanation and updates.
The actual 500 Internal Server Error issues are caused because the migrations are still in progress. Our administrators are working on fixing a few issues, and cPanel occasionally becomes unavailable due to the fact our systems are still trying to re-create and migrate thousands of accounts as quickly as possible.
This should be fixed soon once the migrations are complete, and an update will hopefully be posted shortly on our status blog explaining the current status.
The freemium model only works if you keep customers happy with your free offering
Some people believe free hosting is a "free trial" of paid hosting, but this is simply not the case. We have tens of thousands of accounts on free hosting, meaning that each free hosting server ends up hosting thousands. On premium, this is not the case - premium servers have much less people on each, and premium servers are subject to less abuse. We also employ a 99.9% Uptime Guarentee SLA on premium hosting, which means in the extremely unlikely event there is downtime, we partially refund customers based on uptime. On free hosting, there is no SLA.
few, poor quality updates
We're doing our best to keep everyone updated, but I really don't see how there is anything more to update you with. We are attempting to migrate tens of thousands of accounts to a brand new platform, and it takes quite a while for the server to finish transferring and reconfiguring each individual account. Our admins are also doing their best to fix any problems that occur in the process.
I greatly appreciate everyone's understanding of the matter and hope the migrations will be complete shortly.
