My Hosting → Summary is the honest picture of your plan: what you are allowed, and what you have used.
What it shows
- Hosting instances used — sites created, against the number your plan allows.
- Disk space — used and available. This covers your files, your databases and your backups together.
- Bandwidth — traffic served.
- Counts for databases, domains, sub-domains and FTP or SFTP accounts.
Running out of space
Old backups are usually the cause. Removing ones you no longer need is the quickest way to free space — see How your backups work. If you genuinely need more, move up a plan.
