Announcement | Binance Support

What is the best way of getting announcements instantly? Announcement page gives it around 2 minutes later the announcement time(For example it is written 12:38 but I can see it on 12:40 maybe because any kind of caching?). But I have seen some telegram channels they provide it as the announcement date. They even announcing before official binance telegram. What exactly is their source? Is there a websocket option for that?

Unfortunately there is no websocket streams for announcement, beside the official announcement page, you are free to subscribe these Telegram channels, they are also easy and convenience channels to get info.
