packagecontrol.io DNS issue #149

Description

When trying to access https://packagecontrol.io I ran into occasional timeouts.
After some digging around (pun intended) I noticed that e.g. the google DNS (8.8.8.8) returns two different IPv4 addresses for packagecontrol.io.
One points to the website I'm expecting the other one results in timeouts on port 443 and a HTTP "forbidden" on port 80.

I noticed that after restarting our primary DNS server and flushing its caches.

If that is a regional thing: I was doing the DNS queries from Germany

The working DNS entry:

; <<>> DiG 9.16.21 <<>> @8.8.8.8 packagecontrol.io
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10320
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:

The DNS entry that leads to some (probably unintended server):

; <<>> DiG 9.16.21 <<>> @8.8.8.8 packagecontrol.io
; (1 server found)
;; global options: +cmd
;; Got answer:
