Google's John Mueller said that moving to a new hosting company doesn't cause ranking declines. Of course he means if the new hosting company doesn't prevent GoogleBot from crawling your site. But in general, moving hosts doesn't have a negative impact on your rankings.
John said on Twitter "Moving hosting results in a temporary slow-down in crawling, but that catches up quickly & doesn't affect rankings." "Moving to a strong & fast CDN (like Cloudflare) makes sense for lots of sites," he added.
This was in response to a case study that showed a one-off where a specific webmaster moved to Cloudflare and their rankings dropped. John clearly is saying this is not true when he said "That post's just speculation."

So do not fear moving to a faster and more redundant hosting solution.
