If you are not able to use your account. You might be blocked by Google from Gmail. It can happen if you mistakenly broke any law or regulation.
If Gmail has blocked, you will know. It wills how a message that Gmail has blocked you. Otherwise if you're not able to open means you are hacked.
Gmail can be blocked as a site on your computer. You have to see on your browser where it has been blocked. Go where it is blocked and then unblock it.

Hacking is an illegal act, therefor you will never know.
If Gmail is blocked, there is no way of getting on to it on that internet connection. Try connecting to another network. Or you could ask the owner of the network to unlock it. There is no way to get on to Gmail on that internet connection beside hacking into the connection, which is not recommended. Sorry if i couldn't help you!
go to net browing Center near to your office by great M.M.M
Go to the top corner of your screen. System Preferences >> Parent Controls >> Then enter password and find "Blocked Sites". That's how it is on my computer, it depends on your type.
Is your school really that protective? They blocked it or something? My school doesn't have a problem with letting us use the computers to log into email to email projects and stuff. If you can't log in, then I don't know what to tell you besides tell your school to allow it. It's ridiculous if they don't let you get on godd*mn gmail.
You cannot know this because of security reasons. The servers are all at the Gmail office. They do not disclose the location because of theft reasons.
Well they don't tell you if they blocked you obviously, because it's a concern of privacy, but you would know if they blocked you if you sent a message or something like that and then if there's no response after a long time, then you know that they blocked you. :P
Your school has blocked certain sites - to try to get you to concentrate on your lessons - not use their computers for personal communication which should be done from home ! We in the Wiki community will not help you bypass your school's security protocols !

There is no such option to view that. Privacy is Gmail does not provide that. You cannot look who filtered you and when.
