Want to store logs? Now you need to make sure you're scrubbing any type of personal information from the logs. Want to use a third-party service? Now you need to make sure that you are using their GDPR-compliant plan, and that you are using their Amsterdam endpoints. Maybe you need to renegotiate your contract with them.
You can put the IP in your security logs because that is necessary to secure the service. Just have a routine to scrub the logs once they are too old to be useful anymore.
You can't put the IP in your shadow profile database and sell it to shady marketing companies, unless the user has explicitly agreed to that.
The question isn't only whether something is personal information or not, it is also a question of what you intend to do with the data.
Not exactly; it's up to the judges to decide whether IP addresses count as personal information as defined by the GDPR (in my opinion they're not, but I can see why one would think differently), so the flaw isn't as much inherent to the GDPR as to the fact that people just don't understand the internet.
While the wording of the Recital leaves some ambiguity as to whether an IP is automatically Personal Data under the GDPR, its specific call-out would make arguing that it is not difficult. This would particularly be the interpretation of American lawyers, who tend to assume that no connection is too tenuous to be held against their client by a shrewd prosecutor or regulator and will thus advise their client to treat all IPs in all situations as Personal Data.
So can Amazon/whoever if they saved the IP alongside other customer information.
But a naked ip->person lookup would require a warrant.
What?! I'm not allowed to store my users name, address and credit card number in my unencrypted syslogs anymore? HOW DARE THEY, THOSE DAMN BEUROCRATS!
Seriously though, while there are problems (like IP address being considered personal information, which they really aren't), the general idea is very positive. You shouldn't be able to store just any information of a person that only gave you this data for a specific purpose. Servers do get hacked, employees do abuse their access to systems and old hardware doesn't always get disposed of properly.
When I'm done using a service, I want my data gone from their servers ASAP, no buts.
Have a look at the list of companies and other websites this service uses/shares data with.
No wonder some websites rather block users all together instead of showing that they are selling data left and right.
