Bugs after the site was down for a while

I suppose the site was under maintenance a week back. Well the site was down for a while and after it was fine,there are a few minor bugs i have experienced,in one of these challenges(i passed it so i dont remember which)there were deadlinks because of which it made it dificult for me to ask for help,Also please improve the node and mongoose challenges as they are not very elaborate and simplified as they should be. Thanks

Thank you for helping make FCC better. Bugs should always be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible. It is important that reported bugs be specific. Contributors need to know which links on which challenge aren’t working, etc.
