Hello,
Sorry that this will be in English.
We do sometimes have downtime this is a problem that we are always trying to improve and will eventually get much better but of course we can't garantee 100% of uptime since we are one of the most searched companys for DDoS protection so we get really large attacks so eventually a downtime of 1 minute once a month or once a week is something that will happen.
But again this will be completly solved really soon we are alway improving our protection.
We will start to have a much bigger network a new locations really soon!
