You can try and get Maxmind to update their database by sending an email to corrections@maxmind.com, but they are terrible at actioning the corrections and only seem to update the database once a month.

Not "seem to" - they do only update it once a month (within the first few days of the month), and openly state this on their website.� You can then factor in a few days to a few months for anyone using the database to download and install the new version.

In general I've found them very good at making changes, especially if you're very clear about the details (eg, the fact they are assigned to you), especially if the whois data agrees with what you're claiming.
