Well, I only have about 200 friends, so it is entirely possible that it's NOT a representative sample. In fact, I'm certain of it. :-) HOWEVER... when I start getting many comments from friends and acquaintances directly after an upgrade and many of us are suddenly having problems using only ONE service (second life) -- and it doesn't seem to matter whether we're using singularity, the SL viewer or Firestorm, it seems to SUGGEST STRONGLY that the problem just might not be with us or our computers* (heavy sarcasm).
Patterns do matter. The pattern over the last several weeks is that the usability of SL has become very iffy for me and many of my friends and acquaintances.
Here's what happened to me... only me of course, so stipulated for the lawyers here... Yes, it's an anecdote, so it's not probative, but it is evidentiary.
I installed the new animesh version 6.2XX of the firestorm viewer and suddenly had repeated crashes in all kinds of situations, sometimes crashing several times within a few minutes. There were times I simply gave up on trying to get on or stay on. I had NONE of these problems with the pre animesh beta. The animesh beta was problematical, but not as terrible as the final version. Then the crashing on tp began to intensify - and I'm not sure that's related to the upgrade, but everything was worse with the upgrade, so it's hard to tell why. For some of my friends, I have started passing them a landmark before/instead sending them a TP offer... so they can log in at the location after they crash during TP.
After about a week of this repeated crashing, I got thoroughly fed up. I downgraded to the last non animesh version of Firestorm.
The repeated crash problem has virtually vanished.
Although I do crash occasionally, and it tends to happen more often on TP, the downgrade has reversed the repeatocrash problem.
Now, I don't know about anyone else, but when I do something and immediately a problem develops, and then i undo the action and the problem immediately goes away, I think there's probably could be a connection.
Further, I have friends who use the SL viewer and who have also downgraded/changed versions and also found their problems have diminished. So it isn't just me.
I seriously doubt my machine has fixed it self at the same time that i downgraded AND my friend's machines have fixed themselves since they downgraded...
Your mileage may vary. I may be newish to SL (3+ years) but I'm not new to the concept of troubleshooting or evidence based reasoning. Just because some of you aren't having problems doesn't mean that a lot of people are not.
Anyway... It's my assessment that there's something wrong with the way SL is running right now... either Linden has created a problem for many, many people, or singularity, firestorm and the linden's own viewer have all had RANDOM catastrophic failure at the same time. It may not affect everyone, but blaming US when suddenly SL becomes unusable when we haven't changed anything suggests that maybe their code isn't as well thought out as it could be.
NOTE: I have had troubles with SL that originated on my computer btw. Therefore, I do tend to check. It's like the help desks always suggest. 1) Is it plugged in. 2) Is it turned on. 3) rtfm. 4) Are you using it right? So, yes, check your own system before you go looking for someone to blame, is a sound idea... but when 9/10 people I talk to have the same problems, originating at the same time, and after the same actions.... AND i haven't found myself having any problems on my computer... well, then I think it's time to start asking the creator of the universe to take a look.

*Well... I suppose it's possible that the game is being designed and customized only for people at the screaming edge of connectivity and resources. Most of us do not fit those parameters, though many of us have made considerable investments.
