I feel this in my bones. Contabo "managed" means you manage while they cash the invoice. Since 2 years on their yearly plan, server down every weekend, no refund policy they say since march but downtime since forever.
Important to read fine print
They sell you managed but when MariaDB chokes at 3 AM it is your problem. Your 4.7G node with 2G per script? That is not upgrade, that is demolition. And their monitoring sleeping through whole business day? I seen this movie. My box was swapping to death, support ticket open 14 hours before human answer.
You got no root, so you cannot fix, but they blame "client responsibility" for PHP values their own cPanel push? Make it make sense. They overwrite your stable config then charge you for privilege of debugging their mess.
Retention promise 3 months, Advocacy deny it. Classic Contabo. Left hand sell you dream, right hand slap you awake.
I been telling forum since 2022: cheap yearly plan is expensive when weekend downtime cost you client. They not managed, they absent.
Since 2017 running CentOS 6 on InterServer box. PHP 5.4. Client saying "server working why change". I Important to them but they not Important to update. Finally hacked last month, they call me "site show casino ads". Now they listen. 8 years. 8 years.
Some host only learn when disaster knock. Contabo not even learn then.
