"Unmetered" does not equal "unlimited." I had a similar plan (but more expensive) for my web site a few years back. I still have the email:
"This is a warning regarding an exceeded quota for the hosting account,
mariahplanet.com
It's already up to 37GB of transfer this month from 7Gigabyte limit. Each GB
transfer is an additional fee of $5.00 per gig. So far it's already up to
$150 for the extra 30Gigs.
This account is affecting the other users inside this server,
Cob2.namesarecheap.com, so please let us know immediately how would you like
to proceed from here.
Options below:
1. Upgrade to Platinum Plan - $99 a month (30 gigs a month and pay the extra
gigs)
2. Get a Cobalt dedicated server for $200 a month (50 gigs of transfer a
month)
3. Suspend the site"
When I emailed all confused, they said:
"Unmetered - meaning not monitored. But if bandwidth of a hosting account starts affecting other users. Hosting account is billed as $5 per gig after the 7gig bandwidth limit."
Maybe that was a little too much info, but I'm just warning you that if you expect a lot of traffic, go with someone that guarantees the GBs, not just "unlimited" or "unmetered."
