Halo Reach issues

I have played Halo Reach for awhile and had no issues but on the date of 5/1/14 there has been a lot of problems.
These problems has affected my K/D severely and has caused no credits to be awarded at certain times.
When I play any matchmaking games it starts to lag out where players teleport or there is a delayed shot from my weapon also if I finish the game it occasionally shows how much credits have been awarded but are not received.
Both my K/D and my earned credits have been damaged due to these issues.
I would like to know if there is a way to recover my credits and or K/D.
I am also not the only one with this issue there has been multiple friends who reported to me that they were having the same issue.

It might be a problem with your Internet connection. try unplugging the internet for a minute or 30 seconds then plug it in again and start up the game.

I thought it was the internet too and I disconnected the Xbox and reconnected as well as when I play it shows a full green bar so it is not the internet connection. I also tested this on other games to make sure it was not the connection and everything else worked fine.

Hi gruntnewbie,

We did not experience any difficulties with Halo: Reach servers on 5.1.14. We recommend reaching out to your Internet Service Provider if this issue persists.
