MyStake, Goldenbet, Donbet, Velobet and Cosmobet briefly went offline after B2B suppliers cut ties

A network of gray-market gambling sites went offline for a short period after several B2B suppliers terminated their contracts. For PSPs and acquiring teams, the useful bit is simple: when upstream providers pull the plug, the operational impact can be immediate, even if the brands themselves are still standing.

1. The affected network included MyStake, Goldenbet, Donbet, Velobet, Cosmobet and other sites.
2. The blackout was brief, not permanent, but it followed contract terminations from a number of B2B suppliers.
3. For payment providers, this is the usual reminder that exposure to gray-market iGaming is not just a merchant-risk question; it is also a dependency question. If the platforms, hosting, fraud tooling, or other upstream services disappear, processing volumes can drop to zero very quickly.
