Missing site back in the serps

I posted last week about keeping an eye on websites, after spotting that 3 of my sites were offline due to my hosting expiring.
One of the sites had been ranking in the top 10 for Induction Loops but because it had gone offline was now nowhere to be found.
I quickly set some hosting up elsewhere, loaded the site up, decided it was a mess so re-vamped it.
Checking the serps tonight for induction loops I was pleased to see it had come back in at number 4, which is probably as high as it ever has been.
I still don’t know how long it was actually offline for, but it is reassuring to see that it came back so quick after being dropped.
