IRR Explorer Error/Issue

Hello Job,

I was wondering how often IRR Explorer queried and updated the IRR databases.

One of our customers updated ARIN IRR entries and IRR Explorer is still showing ARIN as missing for them, although the ARIN WHOIS entry is there. Although ARIN has had the WHOIS entry there for several days.

Thank you,

Kevin McCormick

Dear Kevin,

I am the maintainer of NLNOG's IRRexplorer and can help.

Thanks for the report! I took a look and restarted the routing sources database replication process. The server appears to be able to serve requests again.

A new version of irrexplorer is in development (by programmers more skilled than me!) - hopefully later this year we can all enjoy it.

Kind regards,
