1
00:00:00,160 --> 00:00:07,279
ah wouldn't it be nice if everything in life were 100 reliable i mean your car

2
00:00:05,839 --> 00:00:11,280
your computer your flaky girlfriend who swears there's

3
00:00:09,040 --> 00:00:15,200
no one else in the picture unfortunately few things are truly reliable and that

4
00:00:13,360 --> 00:00:20,240
includes the websites that you count on to be around when you need them even

5
00:00:17,279 --> 00:00:24,480
those sometimes go down but riley don't most big sites live on powerful

6
00:00:22,160 --> 00:00:28,720
geo-replicated servers dedicated to web hosting how does this happen

7
00:00:26,880 --> 00:00:32,640
well there are plenty of reasons a simple but common issue is that some

8
00:00:30,640 --> 00:00:37,120
websites aren't actually set up to deal with tons of traffic you see just like

9
00:00:34,880 --> 00:00:41,600
your home pc and internet connection a web hosting server only has so much

10
00:00:39,360 --> 00:00:46,640
bandwidth on its incoming connection and also only has so much processing power

11
00:00:44,239 --> 00:00:50,480
to handle all of those requests so if a smaller website isn't equipped for a

12
00:00:48,480 --> 00:00:54,399
sudden influx of visitors because some celebrities compromising photos got

13
00:00:52,320 --> 00:00:58,399
posted there you might have a hard time accessing it and you also might want to

14
00:00:56,320 --> 00:01:03,280
think about your life choices a similar but more malicious cause of website

15
00:01:00,320 --> 00:01:07,200
difficulties is the dreaded ddos attack so the idea here is to do what we just

16
00:01:05,199 --> 00:01:12,799
described overwhelm a server with requests rendering it effectively

17
00:01:09,200 --> 00:01:16,000
inaccessible except it's on purpose the

18
00:01:12,799 --> 00:01:18,000
first d in ddos stands for distributed

19
00:01:16,000 --> 00:01:22,640
meaning many connected devices some of which may be part of a botnet attack a

20
00:01:20,320 --> 00:01:27,680
server at once the motivations behind these types of attacks vary greatly as

21
00:01:25,200 --> 00:01:31,920
wise old alfred put it some men just want to watch the world

22
00:01:29,600 --> 00:01:36,560
bone and you can learn more about them right up here but a server being too

23
00:01:34,400 --> 00:01:40,320
busy to handle requests is just one reason it can go down sometimes there

24
00:01:38,640 --> 00:01:44,720
can be problems with the hosting service itself which can be caused by anything

25
00:01:42,320 --> 00:01:49,200
from a hardware or software problem to a malware attack to even a natural

26
00:01:46,720 --> 00:01:53,680
disaster and that's where things really hit the fan because if one of the web's

27
00:01:51,280 --> 00:01:59,040
major hosting providers is affected the outages can be widespread for example

28
00:01:56,560 --> 00:02:04,560
cloudflare handles hosting for a billion ip addresses and 10 of the fortune 1000

29
00:02:02,560 --> 00:02:10,399
so a problem with a service like that can cause outages or slowdowns all over

30
00:02:07,040 --> 00:02:12,560
the internet as it did on july 2nd 2019

31
00:02:10,399 --> 00:02:17,040
when a ton of sites went down due to a huge spike in CPU usage another common

32
00:02:15,360 --> 00:02:20,720
issue is a problem with the site's address sometimes a website will need to

33
00:02:19,040 --> 00:02:24,080
change its ip address which you can learn more about up here

34
00:02:22,400 --> 00:02:28,080
so trying to punch in the domain name that you're used to will result in the

35
00:02:26,000 --> 00:02:33,200
browser being pointed to the wrong ip address and likely a page not found

36
00:02:30,879 --> 00:02:36,400
error until the domain name system or dns gets updated to reflect the new

37
00:02:35,519 --> 00:02:41,840
address other kinds of simple user errors are surprisingly common a system

38
00:02:40,000 --> 00:02:46,560
administrator can forget to renew the domain name leave a cable unplugged

39
00:02:44,160 --> 00:02:51,440
misconfigure ports neglect to set up backups and even just spill their diet

40
00:02:48,480 --> 00:02:55,920
coke onto a server rack yet klutz and finally sometimes the issue doesn't stem

41
00:02:53,360 --> 00:02:59,599
from a problem at all sites need maintenance to update code or hardware

42
00:02:58,000 --> 00:03:03,680
and oftentimes they have to be taken offline for a short while while this

43
00:03:01,519 --> 00:03:07,599
happens now many organizations have plans for this to minimize downtime such

44
00:03:06,000 --> 00:03:11,440
as performing maintenance at times when they're not expecting much traffic and

45
00:03:09,599 --> 00:03:14,959
larger companies like google can serve users from an alternate location if one

46
00:03:13,680 --> 00:03:20,080
of their other servers needs to be worked on however if an error occurs

47
00:03:17,519 --> 00:03:24,159
during an update downtime can last much longer than expected and a final tip is

48
00:03:22,159 --> 00:03:27,680
that if you can't access a website but you're not sure whether the site is

49
00:03:25,840 --> 00:03:32,560
actually down or not there's a great site called down for everyone or just

50
00:03:30,000 --> 00:03:34,959
me.com that you can use to check in on all the most important hotspots on the
