Dear Customer,
Unfortunately, Comodo CA Upstream Provider is having problems again due to overcrowded orders. Right now, an emergency maintenance takes place to fix the issue Comodo is experiencing.
Why does it happen?
Comodo servers are not as reliable as other CA servers, and due to the fact that Comodo is issuing a very large amount of orders, it occasionally experiences technical failures.
When will the certificates be issued?
There is no ETA for solving that problem. However, current SSL certificates that have processing status will be issued with delay. It should take not more than several hours to issue those certificates.
We apologize for any inconvenience you may have. Meanwhile, if you need a reliable SSL certificate issued as soon as possible we recommend looking at the following SSL certificates:
Thawte 123 SSL - of the most reliable DV SSL on the market with the best browser compatibility.

Cheapest DV SSL, RapidSSL Standard Certificate - That's one of the most well-known cheap certificates.
