Provider problems since 2 weeks

Since 2 weeks my provider has problems. First, some minutes per day and now a few hours per day offline.

They are working on a solution…

My online-time now is round 94% and the number gets smaller.

Can this be the end of my round 1 year old node?

The online score is calculated for the 30 days. If online score would drop below 60%, your node would be suspended (no ingress) until the online score would recover above 60%.
The node can be disqualified if it would be suspended again during the review period of 30 days or if it was more than 30 days offline.
Your node should be online for the next 30 days to fully recover. Each downtime event will extend the required period for recover to another 30 days. The review period would not be extended.
