Please help! can't log in to my openhab webpage!

Hello i am using openhab 1.8.1 on raspberry pi 3, everything worked fine last week but today when i log into https:/// the web browser could not open and said it took too long to respond… Could anyone show me why? Thanks in advance!
By the way, it seems that often crashes down because sometime I cannot log in to this page, I hope the openhab’s technical team could fix it

There is a known issue with the my.openhab servers that is actively being worked. There has also been a massive attack against major internet infrastructure today that has affected such major sites as Netflix and LinkedIn which also could have caused some problems.
