Anybody on three get an pdp authentication error this morning?

Hi all, just checking if anybody else has had intermittent network failures this morning? I had a message of pdp authentication error, could not connect to cellular data. It seems that the issues is with three. Now their my3 page is down for maintenance.
What I did to restore mine.
Take out the sim card.
Hold the home button and power button together until the apple logo appears.
When it turns back on, insert the sim card and try again.

This worked for me, but it may be necessary to reset network settings too.
