Central Repository IP Address Change?

[Paul Brown]

Hi,

It seems the IP address for repo1.maven.org has changed twice in as many
days.

Last week it appeared to be 38.97.124.18. Yesterday I noticed that it had
changed to 63.246.20.112. Now today I see it is 207.223.240.88.

$ nslookup repo1.maven.org 8.8.8.8
Server: 8.8.8.8
Address: 8.8.8.8#53

Non-authoritative answer:
Name: repo1.maven.org
Address: 207.223.240.88

Normally, this wouldn¹t be a problem, but the server on which my Nexus
repository manager runs resides behind a firewall. My IT department
requires that we firewall connections from our servers to the internet using
the destination server¹s IP address. A shifting IP address requires that I
keep bugging them to change the firewall rule, all while my developers are
trying to download new dependencies.

I wonder, was this IP address change planned? Will the IP address continue
shifting in the next couple of days? How can I be notified of any changes
in the future?

Thanks,
Paul

The ip change is part of some networking and hosting upgrades that
we've undertaken to ensure the stability of the repository. We
actually have 4 systems now that could be serving Central at any given
time. There are 2 hosts in the UK and two virtual machines in the US
(served from a 6 node cluster).

The IP you see today is the one we intend to maintain going forward,
but you should allow rules for the following IPs just in case things
are failed over for any reason:

207.223.240.88 : US primary
207.223.240.92 : US staging / standby
89.167.251.252: UK Primary
89.167.251.253: UK standby
