Migrating PF to New Host: Minimal Downtime Expected

[symbolipoint]

How long was your downtime? For most people it should have been very quick. We switched around 6:30am this morning.

Less than 1 full day;
Maybe not more than 12 hours.

We're going to hop on a zippy professional DNS server so the downtime should be only a few hours compared to the usual 24hrs wait on propagation.

What was the TTL setting? Verizon's DNS was giving me the old IP until just a few minutes ago.

Yesterday it was 60 for much of the day, but it's apparent some ISPs cache for much longer. Hopefully everyone is over now because I put into cancel the old server tomorrow.

I landed already yesterday in the middle of hurricane seasons ...

I've been looking at the usage on the old server, and it's completely dropped off now, so it would appear everyone is now on the new server.

It was more than 24 hours before I was able to get back on.

Executive Summary:
PF is moving to a new host with better hardware and prices. The move will happen sometime this week. Expect a few hours downtime.

More Detail:
Our current host has told me the datacenter that holds PF's server is closing within the next couple months. Instead of moving to a new datacenter with the same host we're going to move to a new host with better hardware and better pricing. A win-win! Because the busy school season is right around the corner we've decided to expedite this process to this coming week and as soon as Tuesday. The process hasn't been fully mapped yet, but the switch could happen either Tuesday, Wednesday or Thursday. I'll of course update this thread once that is figured out. We're going to hop on a zippy professional DNS server so the downtime should be only a few hours compared to the usual 24hrs wait on propagation. So expect this week that you may receive an error when visiting PF, but don't panic. Try again in a few hours.

Disclaimer:
I've always been correct about downtimes in the past. It's never been more than I've said.

Thanks sir...…..i hope son i get answer, have a nice day……...

For me things were really simple. No "hurricanes", no take-off, no landing either. It seems "I slept" thoughout the whole thing! ...

Looks the same to me (so far) ...
And so far so good.
By the way, I didn't know there was another Staff Administrator other than @Greg Bernhardt !? ...

Let me introduce you to Matt. He helps with some of the highly technical aspects of the server.

Hi Matt! Seems you guys have been doing quite a work. Our congratulations and admiration! ...

Has the time zone changed for the day shown on post? e.g. https://www.physicsforums.com/threads/random-thoughts-part-6.875108/page-209#post-6042044

It's Wednesday here Central standard time zone. Wasn't the old server located in this time zone?

Server is on the east coast now

That explains it. Thanks Greg.

You can set the time zone in your profile, by the way.

Is it just my impression (on my end) or red alerts take longer to appear? (without refreshing ...)

I have only noticed small interruption. Mostly, they appear as normal.

Live updates of alerts without refreshing are a gold membership feature.

Live updates of alerts without refreshing are a gold membership feature.

" Live Update
The Live Update feature is very exciting and useful. This feature polls the database every 10 seconds for any new alerts or conversations regardless of refreshing or if you are even viewing the browser tab. You could be writing a post and get an alert or be checking your email and see the browser icon change to alert you of a message. I love this! "

That's different! [I don't have those yet]
I meant just by "viewing the browser tab" (without refr...).

Let me investigate this further on my end, before I bring this back (e.g. to Greg or Matt), to make sure it wasn't temporary. It's not a big deal anyway. No other changes noticed so far, everything's great, the forum still superfast everything else otherwise ! ...

 

[jim hardy]

got bumped off mid post maybe thirty minutes ago. Got a 'security error' message when tried to log back on.
I don't know how i got back on, i think 'back arrow' on browser
but thank goodness my long long post in progress hadn't disappeared

it was the recent transformer thread inquiring about 5- & 60 hz in EE.
old jim

ps @ still won't autocomplete

 

[fresh_42]

@jim hardy autocompletes here. However, there seem to be stability issues with the server connection. I think I had an hour or so downtime (no pings) yesterday and for some seconds some minutes ago.

 

[jim hardy]

@fresh_42
worked that time

 

[jim hardy]

@fresh_42

worked again
maybe it's user specific?

@Tom.G

worked again

@jim hardy worked again

intermittent ii guess.
Computers are just that way, ever since @Microsoft
EDIT oops i see we have a user by that name. Sorry , fellow, not you personally.

May be it's Microsoft itself with a robot account or something ... (I see no activity ...)

but thank goodness my long long post in progress hadn't disappeared

Draft gets saved fast in the system always anyway.

Waited a few days. It seems fast and normal now in all respects ...

Hey Greg, that was fun! Can we do it again?

 

[dlgoff]

@Greg Bernhardt
I've noticed log-in time is much faster now.

 

[Borg]

People log off?

 

[jim hardy]

@Greg @ still doesn't autocomplete i clicked on Greg Bernhardt , gut just Greg showed up.

@Greg Bernhardt worked second time.

Well there is a member @Greg. Typing @Greg , (with the space), brings up Greg Bernhardt at the top of the list.

 

[jim hardy]

Yep Clicked Greg Bernhardt and it didn't autocomplete - first time. Did on secomd try. Some bit someplace gets changed after first try.

Just a minor annoyance.

[symbolipoint]

I do log-off. I use private-mode in browser anyway, so if browser were closed, I would be automatically disconnected from physicsforums. I would then sign-in again when I want another session on the physicsforums.

It's intermittent here, as is occasionally the banner at the page top doesn't show until the first scroll action. Both worked this time.
