I noticed this post today, and my cart's canada post shipping module settings still reflect the 216.191.36.73 IP, and it's still working here. Is this a "gradual" turnover that you know of?
yes, it is.
There was a period yesterday that your site wasn't working - whether you knew it or not - because the 216 ip was totally down. It appears to be back up now. Probably due to customer complaints. Still, its a good idea to make the switch.
