This is a major issue and the 'hot servers' on the official website is bugged or not working properly. please fix this ;/
It is not a major issue as you state. But yes, it is a issue.
Do you have any AdBlocker on? If pause it for leet.cc, you'll realise that it works. For example this screenshot below.
Any image file that get's updated, most AdBlocker will block it.
It's your AdBlocker's way of keeping you safe from anything that it becomes slightly suspicious at.
We do also know about the offline servers issue. (I have a strong guess that this is what you mean)
