Knowing the difference.
WHEN AN UPGRADE IS THE RIGHT ANSWER
Genuine visitor traffic exceeding what the plan provides, after caching Disk or inode requirements that cannot reasonably be reduced An application legitimately needing more than the plan allows Sustained growth
WHEN IT IS NOT
Slowness that caching would fix Resource use caused by bot traffic A single heavy plugin A backup running at a bad time A one-off spike
HOW TO TELL
Fix the obvious causes first. Then look at usage again.
If it is still at the limit with caching enabled and bots controlled, the need is real.
WHAT WE WILL TELL YOU
Honestly, which applies.
We would rather you stayed on a plan that works than upgraded to a plan that does not fix the problem.
WHAT TO SEND US
Your usage figures, what you have already done, and what the symptoms are.
WHAT AN UPGRADE DOES NOT FIX
A site that is slow because of how it is built.
A larger plan runs the same problem faster, for a while.
