They have, like, an incidence every two days? That's utterly disturbing, does anyone actually pay them?

For political reasons we buy a tonne of their certificates. It's not uncommon that I'll paste a CSR into the interface and just get a quality error like "Unhandled Exception", which basically tells me that they fixed it. Because back when it was Comodo I used to see full page stack traces.

The blue ones are planned maintenance and reading the contents indicates that it's mostly changes and fixes for the customer-facing UI. It may be a bit excessive to post all of these, but they certainly don't indicate any sort of problematic issue with their software.
