ProtonVPN is doing a major upgrade in its infrastructure:
```
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Apr 09, 2025 - 11:30 CEST
Scheduled - In the following period from the 9th of April up to the 30th of April, various Proton VPN dedicated servers will be in temporary maintenance mode, for a short duration period, in order to allow us to perform a major infrastructure upgrade, paving the way for overall increased performance and efficiency of our Proton VPN infrastructure.
We apologize for the occasional inconvenience.
Apr 9, 2025 11:30 - Apr 30, 2025 23:30 CEST
```
Let's wait if it works again in the future...
The `suffix_id` is simply an incremental index (see
`ndpi_load_domain_suffixes`), so its value might changes every time we
update the public suffix list.
- ndpi_load_domain_suffixes()
- ndpi_get_host_domain_suffix()
whose goal is to find the domain name of a hostname. Example:
www.bbc.co.uk -> co.uk
mail.apple.com -> com
