There are many reasons why a page has been blocked. This ranges from unpaid bills to scam and suspected spam (of course, does not mean that I assume a scam). Basically, a provider only takes a website offline if it may damage its infrastructure (financially, reputation, ...). This could also happen, for example, due to attacks / DDoS, malware, etc.
Stake.com will definitely do everything possible to clarify the facts and bring the website back online as soon as possible. Ev. StevenStake can also say more about it, he is probably the one who knows best what is currently the problem and why the website is offline.
i dont experienced this problem yesterday because im already logged on but i see on the chat that many are complaining so i tried opening the link on another tab and it shows me this erorr .
this happen also on primdice too , support said it was some kind of technical issues and there is no point of worrying . few hours later the site is up and running fine again . stake and primedice have same owner tho , and primedice is an old casino so there is no need to suspect that they are turning into a scam .
