There are some times, that we experienced an error in our Steemit account, and we cannot do any transaction with our account, sometimes we have encountered or received an error message, that says bandwidth limit exceeded, then what is the meaning of this error message? Each of our account have a bandwidth allocated, each time we made any types of transactions, like when we are upvoting, resteeming, commenting, following people, making a post, transferring SBD or STEEM and any other transaction, it consumes our bandwidth. Once you consumed all of your allocated bandwidth, and the green bar at https://steemd.com/@username (change this with your username)turns to gray, you can't move or do anything, in short, your account are going to be frozen for a few hours, but you don't need to worry about that, because after few hours, it will going to get back to normal.
The reason why, they only allocate a limited bandwidth to each account, is to limit the spam to the site, and if you only have a very few Steem Power, then your bandwidth limit is very small, so you also have a limited activity within the website. People who have more than 100 Steem Power, is almost not affected to the bandwidth limit, but to those who have a very few, then expect it to happen, every time that the site is congested with lots of users online, because they also reducing our bandwidth limit, when there are lots of people who are online.
If you encounter this bandwidth limit error, then you don't need to worry too much, because it is a good feature of the Steemit, they are just fighting against spam, to protect the interest of many people and in order for the website to live longer.
