I think your post really doesn't have anything to do with the actual issue mentioned in this thread, marissa. For example, this pearl of wisdom:
Maybe your website bandwidth exceeds the limit provided by the web host
They would know if they were over the bandwidth limit, which is nearly impossible with shared hosting to go over that anyway since it is unlimited there. Additionally, this customer had a new account and had just moved to Lunarpages at the time.
Or maybe the hosting that you use is up and not be extended again...
Next, if their account were expired for hosting, it would auto renew. If they chose to not renew it or let it lapse, I would think they would be aware of that as well. Again, this customer was new, so it seems unlikely the hosting would already be expiring, since it just had started.
None of the comments made have anything to do with disappearing from Google due to DNS propagation or moving, which the customer already explained happened. You have made multiple posts for the last couple of days to older threads in this fashion where the comments elicited do not pertain to the actual thread topic, so let's hope you will start reviewing what the topic is about prior to responding to it. Or to put it another way:
Thanks for sharing information about that...And hopefully you are given more information by first reading all posts thoroughly before replying.
