 ## Known bugs and limitations
 ### General
-* The ping/jitter test is measured by seeing how long it takes for an empty XHR to complete. It is not an acutal ICMP ping. Different browsers may also show different results, especially on very fast connections on slow devices.
+* The ping/jitter test is measured by seeing how long it takes for an empty XHR to complete. It is not an actual ICMP ping. Different browsers may also show different results, especially on very fast connections on slow devices.
 ### IE specific
 * The upload test is not precise on very fast connections with high latency (will probably be fixed by Edge 17)
 * On IE11, a same origin policy error is erroneously triggered under unknown conditions. Seems to be related to running the test from unusual URLs like a top level domain (for instance http://abc/speedtest). These are bugs in IE11's implementation of the same origin policy, not in the speedtest itself.
