Remove *.cz domains from WMF's infrastructure
Closed, ResolvedPublic

Description

Hi,

all *.cz domains related to WMF projects are owned by and managed by Wikimedia Czech Republic (WMCZ). For some time, NSSET for this domain was set to WMF's name servers and handled by WMF's infrastructure. As this made some SSL certificate related problems (T152622), to resolve them, I changed NSSET to WMCZ name servers and changed A/AAAA to WMCZ webserver. Therefore, nothing related to any of those domains should be necessary in WMF's infrastructure. To keep clear configs, they should be purged IMHO.

Best regards,
Martin Urbanec
WMCZ sysadmin

For the record, this is the list of domains owned by WMCZ. All those domains should have non-WMF NSSET and non-WMF webserver.

@Urbanecm fyi, i think this one domain is different from the others:

wikizdroje.cz has address 198.35.26.96 (that's WMF)

all others are pointing to 81.95.96.75 (.cz)

Also i was wondering what about mail? It looks like the MX records are pointing to wikimedia.org for all of them.

@Dzahn: Thank you. I simply forgot to update NSSET to the new one. https://www.nic.cz/whois/domain/wikizdroje.cz/ says NSSET was changed, so I guess it should propagate soonly.

Ad mail) It's relict, when changing the NSSET, new DNS pulled DNS records from WMF NSSET. When I updated the IPs to not point to WMF anymore, I simply didn't delete the MX records. Will do it sometime.

I created T208122: Remove MX records pointing to mx1001.wikimedia.org or mx2001.wikimedia.org from WMCZ's domains for this.
