Broken tracking links

I tried to switch over to SSL for our tracking links and it looks like something got awry. I need to follow up with CloudFlare as to what the issue was (it was likely a misconfiguration on my end, in all honesty, but hard to say) — but for around two hours all tracked links were broken because they pointed to https and not http. I've reached out to the folks who have sent outbound emails during that time, and am in the process of backfilling the transactional emails (such as subscriber confirmations) that were sent during that window!
