I read the complete thread. Sitting on your hands is not a solution. You can change the php.ini if you actually take the time to build one. By not building one you are putting yourself in a position of dependence.
Noone has to be a mind reader. We are paying for webhosting, not support for 3rd party scripts. It isn’t a host’s responsibility to communicate with their customers, although I agree it would be in their best interests and as far as I’m concerned DH do a damn fine job of it. For starters, acknowledge that you have a problem and pay attention to how you can remedy the situation yourself. If you do so, the next time something like this happens you will be in a position where you won’t suffer the downtime you appear to have had ‘this time around’.
Posting doesn’t help at all. Proactive administration does.
