I believe same thing is happening as last time.  You are seeing the difference on those nameserver because they are carrying different serials. If you see, both bd-ns.anycast.pch.net and dns.bd are behind. I just checked and zone transfer seems working from the .bd master to PCH server but we are missing the notifies, so seems, we are falling back to refresh time set on their SOA record.

$ dig +nssearch com.bd
SOA dns.bd. root.dns.bd. 2017010124 14400 3600 604800 86400 from server 204.61.216.108 in 8 ms.
SOA dns.bd. root.dns.bd. 2017010129 14400 3600 604800 86400 from server 203.112.194.231 in 225 ms.
SOA dns.bd. root.dns.bd. 2017010129 14400 3600 604800 86400 from server 203.112.194.232 in 227 ms.
SOA dns.bd. root.dns.bd. 2017010127 14400 3600 604800 86400 from server 209.58.24.3 in 313 ms.

BTCL should really properly and seriously check their registry portal. May be get someone to pen test it properly and fix the loopholes.

Thanks.
