Looks like adcli was unable to detect your site - you found a bug in adcli. O.

The site discovery is not related to DNS. adcli (and btw SSSD as well) run a LDAP search like:
ldapsearch -H cldap://se-dc01.infinera.com -b '' -s base "(&(DnsDomain=infinera.com)(NtVer=\06\00\00\00))" NetLogon
The result is a base64 encoded blob which contains various data about the domain. This data might include the site of the client but it might be empty if the AD server cannot determine to which site the client belongs. Please note that the only information the AD server gets from the client is the IP address.
But I agree with Ondrej that this should be fixed in adcli. If the client site is not available or empty a site aware DNS lookup should not be tried.
Nevertheless I would like to ask you to send me the base64 output of the ldapsearch command from above so that I can check if e.g. the blob is in a format adcli currently does not expect.

I think the original idea was that if 5 servers do not reply there might be something wrong in the environment and it does not make sense to query more and more servers. Do you think DISCO_COUNT should be configurable or wouldn't it be easier to use the -S option to specify a suitable DC?

So it seems computer-site above is empty and domain-controller-usable = maybe looks odd too. I think it could be caused by our DNS server but I don't know what to look for
The site discovery is not related to DNS. adcli (and btw SSSD as well) run a LDAP search like:
ldapsearch -H cldap://se-dc01.infinera.com -b '' -s base "(&(DnsDomain=infinera.com)(NtVer=\06\00\00\00))" NetLogon
The result is a base64 encoded blob which contains various data about the domain. This data might include the site of the client but it might be empty if the AD server cannot determine to which site the client belongs. Please note that the only information the AD server gets from the client is the IP address.
But I agree with Ondrej that this should be fixed in adcli. If the client site is not available or empty a site aware DNS lookup should not be tried.
Nevertheless I would like to ask you to send me the base64 output of the ldapsearch command from above so that I can check if e.g. the blob is in a format adcli currently does not expect.

Så there are lots of servers but only the 5 first vill be queried and most of them will not answer our requests. Should local DNS be configured differently?
I think the original idea was that if 5 servers do not reply there might be something wrong in the environment and it does not make sense to query more and more servers. Do you think DISCO_COUNT should be configurable or wouldn't it be easier to use the -S option to specify a suitable DC?
That makes sense, I think we have a mess somewhere ... This is a bit odd thogh: adcli info -v -S se-dc01.infinera.com * Sending netlogon pings to domain controller: cldap://10.210.34.21 * Received NetLogon info from: se-dc01.infinera.com [domain] domain-name = infinera.com domain-short = INFINERA domain-forest = infinera.com domain-controller = se-dc01.infinera.com domain-controller-site = Sweden domain-controller-flags = gc ldap ds kdc timeserv writable full-secret ads-web domain-controller-usable = maybe [computer] computer-site = Sunnyvale
Still says computer-site = Sunnyvale when I am in Sweden. I guess we need to check where our network belongs

I'm not sure what you think might be wrong here? The client site name should not change even if a server from a different site is queried. So even if the server is in the site Sweden the client is still in Sunnyvale.

Both SV-DC01.infinera.com (from the adcli output) and se-dc01.infinera.com (fomr the NetLogon reply) say the site is Sunnyvale, maybe this is the default site?
adcli will take the response from the first server that replied, if it is from the same site as the child. If not it will wait for another reply. This is what you see the in output. The first server that replied se-dc01 is in a different site (Sweden vs Sunnyvale), so adcli waits and the second reply from sv-dc01 is taken. If all servers replied or a timeout of 15s is passed an no DCs from the same site replied adcli with pick the first proper reply.
