It seems LTC Casino's main website (ltccasino.com) is currently facing some availability issues.  There's a chance they could be experiencing a DDoS attack, which overloads servers with fake traffic.

In the meantime, you can access LTC Casino through their alternative domain at https://ltccasino.io.  They shared this new URL on Bitcointalk ANN and Twitter to alert customers.

However, situations like these draw scammers attempting phishing schemes.  Double-check any links come from legitimate sources before entering personal information or making transactions.  Stay vigilant against fraudsters trying to exploit confusion around the website changes.
