Does twitter randomly not send sms messages?

[original_pet]

Very frequently I won't recieve random tweets through sms but they are on the website. I use Verizion.

Does this happen to anyone else?
Anyone know what to do to fix this?

When the twitter servers are busy, they can get overwhelmed and fail to send SMS. If you get a lot of updates, you're much more likely to notice this behaviour. The only thing you can do is reduce the number of people you receive updates for.
