The vertical access shows the "Full Webpage Response Times". The lower the value, the more desirable the result. If this parameter isn't explained to the reader, they may think that a higher value is better.

The blue bar shows the companies "Median Time". Notice how it typically resides at the middle of the industry IQR (interquartile range) green bars. The IQR is the distance between the first and third quartiles, and it gives you the range of the middle half of a data set. Since this companies median is within the middle of those green bar, this suggests that the middle speed values recorded for customers are no different than the industry standard. On the other hand, the averages are notably higher than the medians, which means the data is skewed to the right.
