Reverse DNS not updated on public dns servers

I have domain, let call it domain1.tld.
It is correctly configured on DNS servers ns.hoster.com.
Whois points to correct DNS server ns.hoster.com.

I can obtain PTR record for this domain, querying ns.hoster.com, like:

[root@myserver ~]# nslookup -type=ptr dom.ain.ip.addr ns.ip.ad.dr
Server: ns.hoster.com
Address: ns.ip.ad.dr#53

addr.ip.ain.dom.in-addr.arpa name = domain1.tld

However...

[root@myserver ~]# nslookup -type=ptr dom.ain.ip.addr
;; Got SERVFAIL reply from 192.168.55.1, trying next server
;; Got SERVFAIL reply from 8.8.8.8, trying next server

Domain itself is resolving ok.

This domain is at least week old, so, propagation must be not an issue.
Could anyone advise, what is wrong here?

What do you mean - "maintained by ISP"?
Like if I add domain with exclusive IP in, let's say, Plesk or cPanel - I must notify my ISP to configure reverse DNS zone?

Sorry for noob questions, I'm not really familiar with this part of DNS.
Strange part here that it is working, if I query authoritative NS, and not working if I query any other, like 8.8.8.8

Yep... the ISP controls this. You can use www.dnsstuff.com to check the entire public domain set, or give us the actual domain name and we/i can do it for you.
