Verizon down half a day, then suddenly free speed upgrade?

Question

Well, this is not a complaint or support, but just curious. I hope its perminant and not temporary
Today 13-Oct-11 I found that the internet was gone for half the day. I got up to use the computer at 10am and notice no connection. Looked at the router and notice there was no dsl signal.  Reset the router, even shut it off and still no signal.. Check the phone and there was a dial tone..
Thought to myself maybe its just a minor outage so will be back up later.. not urgent anyways.  You would see the router DSL light turn a evil red color, and then go off, at one point the light stayed red for 30 sec before going out again.  2PM no internet still, I threw my hands up and said, well better stop slacking and get some errands done. Went out and came back about 5pm and the internet was up. I thought great its back..
Then sometime around 8 or 9 PM EST, the internet went down again.. and it had trouble connecting... so I thought to myself.. oh no not another outage.. about 5 min later the internet came back... but this time... I got faster speed then I normally get! I thought to myself AWSOME!!
How much faster did I get?
Normal 1784kbps down
                  384kbps up
Now I remember back then when they offered 3Mbps for the price I was paying, the person on the phone said that the 1.5Mbps was the best I can get for my line.. so I gave up and kept the default one, then after the outage I now got much better speed. I still don't get the 3Mbps.. but I think it was a fair trade... my new speeds are...
 New Speed: 2112kbps  down
                          832kbps   up
I checked the router and notice that the signal noise is the same nothing has changed, just suddenly more speed. I got OVER 2x the upload speed!! and a 300+kbps speed increase! This came after that weird 5 min of downtime we had.. We have more upload speed then what was given to residentials on the website.. ( can't find it now) Residents suppose to get up to 448Kbps upload and business suppose to get up to 1mbps on there ultimate plan but 768Kbps on the plans below that.
I really hope verizon did not make a mistake and everything will revert back to the old values, otherwise I might have to bug and call verizon to give me higher speeds because I know I can take it..
I just wonder if I reached my router limitation.. The router I have is a Westell 327W that is sort of going bad, was going to bug verizon to see if they will give me a new one, but since I got these much better speeds I don't wanna switch it out now 
Here are my router stats if anyone is curious:
Transceiver Information          Downstream Path            Upstream Path              
DSL Speed (Kbits/Sec)                            2112                            832
  Margin (dB)                                                   20.5                          10.0
 Line Attenuation (dB)                                  53.0                           31.5
 Transmit Power (dBm)                              17.1                                   11.9
Since technically the 2112 is withing the 3Mb limit I hope I get to keep it, also I hope to keep the upload speed though I wonder if they set it to high since customers are suppose to be limited to 448Kbps? don't get me wrong I love the new upload. Websites and games seem much faster since we have had problem with people playing multiplayer while someone else is trying to load a video.
P.S The westell 327W Is the first or second gen it is only ADSL and not ADSL2 it is the A90 series.
P.P.S. I did a IP lookup and it looks like its about the same location though I don't know where the nearest co-location is so I assume its based about the area where the IP is?
Also anyone know if verizon has a new 2Mb tier setting? I think I read somewhere, they set you to 1.5Mbps tier or 3Mbps tier, but never heard of a 2Mb tier.
I do have old copper phone wires.. still hoping one day I get to at least 3Mbps.. but until then. I am acutally happy with these new speeds, (hope I don't see new charges and hope it don't revert back to the old 1.5mbps or nerf the upload speed. I kinda like having better upload for playing games with others online.)

Almost the exact same thing happened to me up in Woonsocket. Except DSL came back on at 7pm. First thing I did was check my stats on my Westell W327 A90-327W15-06 (had since 2005):
DSL Speed (Kbits/Sec)     2112     864
Margin (dB)     16.0     10.0
Line Attenuation (dB)     49.0     31.5
Transmit Power (dBm)     16.7     11.9
The margin drops to 14 but the connection speed is still the same!! Was really thing of jumping to Cox (only other choice, if you call it that, in RI), for the past several weeks my speed would drop to below dialup speeds for a few hours a day. I know it's not on my end as they put a new drop from the pole to my house last year replacing the old wire that had been here since at least the '50s!! But if the speed stays I'll stick with Verzion as long as the price doesn't go up again. I noticed they jacked up my DSL portion of my bill $2 again to $33.99 and calling it Internet Extra.
