[8 July 2026]
Microsoft has decided that the regular SNDS Access Keys will now expire every 30 days.
This will require anyone using the Microsoft SNDS Access Keys on our platform to manually renew them every 30 days, which is, of course, tedious and not ideal.
Furthermore, due to poor design, the old Microsoft API that uses SNDS Access Keys will intentionally return 404 HTTP responses for both expired Access Keys and ‘no data found’ (i.e., your IPs are not blacklisted). This makes it impossible for our system to determine whether your Access Key is valid and your IPs are clean, or whether your Access Key has expired, leading to inconsistent SNDS monitoring results and signals.
We have since implemented a new access method that does not require manual renewal and has no ambiguous mixed return signals as described above. You can connect your Microsoft account at any point, as shown in the following guide:

We urge everyone to switch to the new system as soon as possible in order to continue your SNDS monitoring uninterrupted.
You can still use the old system if you’d like. We’re just marking it as ‘deprecated’, but it will still function as before. The only major downside to it will be that you’ll have to manually renew your SNDS Access Keys every 30 days, and if you ever forget to do so, your IPs will be marked as not blacklisted on SNDS even if they are.
