Yeah this week I couldn't connect to mine several times. Currently it is offline for me. If this happens again I am switching VPS providers. :\
You're not the only one.
Quick Review of Berman Hosting...
Pros
+ Cheap
+ Good support
Cons
- Unstable
I've been using Berman for over 4 months, and in that time the VPS server that my 'node' was on went down about 7 times, i.e. I left software (e.g. Scrapebox) running overnight, and when I woke up, the VPS PC had been hard rebooted, and the software that was running had been shutdown. I do backups, and also Scrapebox has backups, so I was Ok. But, what is annoying is having to setup the software again. Berman could run SENuke or similar, but if you run campaigns for days/weeks, I would not recommend them, because of the instability I experienced. Although others may have a different perspective, bear in mind this is my experience only.
A lot of these newish/cheap hosting providers are essentially one man bands who rent space off data centers and resell to their customers. The guy behind Berman: 'Sven' is Ok, but overall, I'd still rate them 5.5/10, but that's only because of the support and price. I know it can be tempting if you're on a budget, but if you need stability, go for a more established provider or even a low spec dedi. Sorry, I cannot give any other recommendations, but check out domaining/hosting forums for consistently good reviews.
